I am newbie diver and I am going for my advanced PADI this weekend to Tioman. I bought my full gear set this adex and want to find the ideal configuration. Looking at the DIR configuration for making it nice and streamlined. DIR makes quite a lot of sense as it focuses on safety and making reaction time less, in case of emergency situation arises. One thing I am in doubt with is the the octopus on a regulator necklace so that I am give my primary 2nd stage to my buddy and switch to the octopus fast.

My BCD : Halcyon Infinity,
Regulator : Atomic aquatics B2 and Z2 Octopus

DIR recommends a unbalanced octopus. But I have a balanced octopus Z2 with a flow control valve which can be very sensitive. I tried the gear in a pool and it tends to flow under light pressure if becomes inverted. If I attach the octopus to necklace and its hanging there it may start to freeflow. Although I need to test this theory in the waters. I can tighten the valve and make it the highest resistance. I will have to test this. I have attached a bolt snap to the hose and can attach it to my D rings in case this doesn't work out.

Any advice from experienced divers on my thoughts.

Are you using a shorter hose for the necklace?

If you attached it with bolt snap to a D-ring and it doesn't free flow, why would it now that its near your neck?

The octopus is on a much longer hose now as its still in base configuration. I don't think I can shorten the primary 2nd stage hose its a proprietary swivel hose. I think tightening the flow control should desensitize it as I can still breathe fine full tightened.

Since you mentioned you are very new diver, I would not recommend to change "Standard Configuration", you should have your Octopus secure to your right heaps, so that your buddy (or anyone who need to share air from you) knows where to grab it. I don't find the necklace a comfortable setup, you have the Octopus cable running across your body and the Octopus tents to swing around. Secondly are you cool enough when someone grab your main regulator and you are cool enough to switch to octopus?

I think for new divers it's not easy to use DIR set up. Especially the long long primary going round the body.

I saw the super long hose wrapped around the diver as one configuration. I don't plan on changing my hoses now. That wrap around definitely looks very complicated to me and it wont be safe for me or my buddy. I just want to find a configuration which I would like and feel comfortable in. I have one D ring on my right chest which I can clip the octopus. I added a D ring to lower right of the BCD. Doesn't get the too much way of cinch system. As I can still adjust harness.

I am definitely a newbie and have a lot to learn. I figured since I am new I might as well start with something tried and tested before I become more set in my ways. Maybe I will clip the octo on side and primary on a necklace near my mouth.

I tried one of those regulator holders that looks like a pear and hated it. Regulator just coming out of it or it started to freeflow.

First off, I personally use the DIR set-up in both recreational and technical diving. To me it's about as simple and straightforward as it gets. The ideology is well thought out and its function has been tested and proven in many demanding situations.

Now moving on to your current situation, in my opinion it's perfectly fine to swap over to a DIR configuration even if you're fairly new. If anything you'll start doing what's right before other bad habits start setting in. What's important is that you have someone to teach you how to properly utilise the tools you have at hand; pool sessions till you're confident in your gas sharing drills and whatnot.

Also ensuring that the people you dive with are familiar with your configuration is also important. Half the time when I dive with others using the so called standard configurations, I can't seem to find their octopus fast enough. In a situation of panic, a distressed diver will most likely go for your primary because that's the easiest to locate. And if your octopus is located on a far-flung place on your bcd then good luck. Picture the scenario, panicked diver snatches your primary while desperately shooting for the surface. You trying to stay calm while at the same time locating your octopus. Of course I'm not saying this will happen every time, but all you need is that one time to thoroughly screw yourself over. In short, secondary regulator (octopus) on a short necklace is the way to go.

Entirely my opinion, so take what you want out of it.

IMO, I think since got those equipment already, try the best and comfortable way to manage it for your coming course, then think of ways to optimise it. You have a course to learn in a short time(this weekend) and keep changing equipment/configuration can mess you up.
In situation, stay claim, think and apply.

Thank you for your inputs. Definitely helps a lot.

I definitely liked the idea of using a octopus on a necklace and would like to give it a shot. Its all new equipment and I just tested it in a pool only till now. So setting it up correctly for would be a goal for me.

Yes I do agree changing configurations can be troublesome on a course and I plan to do it if I get a few leisure dives at the end. I also have 2 more trips planned after this including a LOB. So would like to setup correctly as I am planning to dive every month this year.

FYI i used these guides to setup the bolt snaps

I personally switched over to the long hose with bungeed octo setup when I had less than 30 dives so I don't think that inexperience should prevent you from switching over to a DIR setup. The DIR setup offers benefits such as having space between divers while sharing gas and better streamlining and is now my preferred open water configuration.

That said, I would advise looking for someone who already dives such a config to help you through the transition because you should ideally have the full picture of why some things are done a certain way vs another way, then it will be up to you to decide whether the DIR way makes sense to you or not. Some options for doing that would be to contact a GUE instructor (http://gue.com/gue-instructors) since teaching the DIR system is somewhat of a specialty of the organisation. A DIY alternative would be to pick up a copy of the following book (http://gue.com/store/books/doing-it-right-fundamentals-better-diving-pdf), which is really a helpful resource for getting started with DIR. If you are really cheapskate, PM me and I'll try to be as helpful as I can :P

With regards to confusing dive buddies with your weird setup, the two uniform length hoses setup that I think you are referring to is by far not as 'standard" as you might believe. A potential issue like this should be resolved with a short pre-dive discussion if your buddy has never seen a DIR setup before.

On your end, you need to get used to the difference between a secondary take air share drill vs. a primary donate drill. Some instructors teach their students the secondary take method, where the buddy reaches for the secondary regulator themselves, but the DIR setup is geared towards the donor actively donating the primary regulator. It definitely helps to develop situational awareness so that you can anticipate and have the opportunity hand off the reg rather than have a frantic buddy yank it straight out of your mouth. Even so, you always know exactly where your backup is, right under your chin.

With regards to free-flow issue of the alternate, I fail to see how changing the hose configuration makes your alternate any more or less likely to free-flow. If you are referring specifically to recommendations which have been made previously for using an unbalanced alternate, I dive balanced Scubapro S600s for both primary and alternate and never had free-flow issues so I wouldn't worry about that unless you plan to dive much colder waters. The venturi valve as you pointed out is helpful for detuning your reg on the fly and I do that with my alternate S600 as well.
