I'm a newbie diver but transitioned to BP/W a couple years ago. 5'10 170lbs First 2 years of diving I rented standard jacket BCs and always wore 10lbs on a belt when diving a 3ml wetsuit and AL80. Since swapping to SS BP/W I wear no additional weights (no wetbelt) and feel completely neutral at safety stop, finishing dives with no air in my wing. I add 4 lbs on a weightbelt when diving with 3/5 hooded vest under my 3ml. Have a 20lb wing for warm water diving, and a 30lb wing in case I dive cold water and thick wetsuits. I have not got my weighting perfected in the cold water setup.
Love the BP/W. Feels very stable, no fussing with weight belt. The only negative thing is lack of pockets, but to be honest I dont really carry anything that needs to go into a pocket for my simple rec dives. Lights on chest DRings, Spool/DSMB on butt DRing, compass and computer on wrists. Slate on forearm, but rarely carry that.
