the prices for these 'reps' are not low.
i would suggest sticking to the real SP Jetfins as there will be resale value should u decide to change.
Am a Jetfins and Apeks RK3 user myself.
undoubtedly, Aropec/Aquatec flippers i prefer calling them flippers, shouldnt have huge differences inwater doing recreational OW dives compared to SP Jetfins. Aropec or Aquatec possibly be a tad lighter/neutral buoyancy ?It could be added advantage for those heavier legged divers to achieve decent trim.
