Frankly, in terms of adjustment, I think that a BP/w has it all over a BC.
Yea it's really not hard to adjust a BP/W, takes a few minutes at most (or no more than an hour if you are making a harness from scratch). Some might be harder to adjust (friend had a lot of trouble with a borrowed BP/W that had a 'comfort harness') but this also applies to some BCs. My old Ladyhawk took me ages to setup and then it would loosen up during a dive - never had this issue with a BP/W.
I've seen HEAPS of new divers have to be shown how to set up their BCs to fit them. I've also seen new divers have to be shown how to make and/or adjust the harness on a BP/W. With the BP/W though, with a basic harness, it can be adjusted to a wider range of sizes and shapes than a jacket/backinflate BC can be.
Hence why I am interested to hear from Valhalla as to why exactly adjusting a BP/W is beyond the ability of a new diver as it certainly does not match my own experience and why I would not consider it to be 'fact' but merely opinion.
