The more you dive, and with increased years of experience and comfort in the water, you will realize you can dive well in any style bcd. But, as you progress in diving. and had bought a jacket, and then progressed to a back inflate unit as I did, you will likely begin to find faults with your bcd as you find better ways to operate. It may simply be something like the location and number of D rings or something more significant, and you will discover, as I did, the only bcd that gives you infinite flexibility is a bp/w. However, bp/ws are not for everyone. For example, my wife has a Scubapro Go jacket, and would not use a back inflate or bp/w because she likes to be higher out of the water while waiting for a boat pickup. You will ultimately find what works best for you, and hopefully you will not have bought several bcds before reaching that level of satisfaction. My bcd progression was plastic backpack and tank (no bcd)...long layoff from diving....Sherwood Avid jacket...Zeagle Covert back inflate...HOG bp/w. Happy now, and would not go back to any of the previous bcd options.
