I curious why you consider the two different. What is your thought process?If you use b/p with crotch strap and weight belt, I think the best is:
- weight belt under crotch strap with drysuit (you have redudancy from wing and drysuit, so there is no need to drop the weights)
- weight belt over crotch strap with wetsuit
I always wear mine under because (when I have weights) my wetsuit tends to compress a little and losing my weight belt isn't my idea of fun. I've been lucky so far and only had it get a little loose and I haven't actually lost it yet.
