sorry I am a little confused
if I am getting a stainless steel backplate, which is heavier, I would need less weight than the aright?
or which plate type that let me carry less weight?
To answer your question....
* If you need 3kg of weight for scuba... and you are using a Steel plate (3kg).... you can dive without using extra weight. But if you are using an Aluminium plate (1kg), you still need to carry extra 2kg on you to dive. Either on a weightbelt or carried on your BCD.The issue here is when you travel by AIR
.... extra weight is extra weight, and every extra Kg
counts when you fly
. Using a Steel plate meant you are adding 3kg to your gear bag..... using Aluminium plate meant you are only adding 1kg. And lets not forget you have to carry your bags around... even if your bags have wheels.
If you have a strong back or big wallet/bank account.... then of course no problem lah
