I also just dove a BP/wing for the first time this weekend. I'm diving dry and am 6'1" 220 Lbs. I was diving a loner rig, as my gear has not yet arrived. I had a DiveRite SS wing, an STA, and integrated weight pouches on the BP. I have a LP steel 95 tank. I wore 12# on my waist, and started with 6# in the pouches. The person doing my orientation added 4 more # during my dive, so I ended up with 22# over and above the BP.
My problem was floaty feet, but I did not have any gaitors, or velcro straps on my legs. I'm hoping that straps or gaitors will cure the floaty feet, as my guide said I didn't need more weight at all. I'm also concerned about my fins adding to the floaty feet, as they're bouyant (TUSA Xpert Zooms), so I'm going to use my wife's blade fins next dive, and see if that helps any.
I liked the fact that the BP harness did not get in the way of my inflator valve. That was my main beef with the rental BC, and that just finally torqued me off a couple weeks ago enough to buy a BP/wings. I was fighting with floaty feet too much to really have a valid opinion of the BP/wing performance. I'm holding my comments until I get my Pioneer and it's been properly fitted and I've dove it a few times. I'm still just too new to diving in general, but I definitely liked not feeling like I was in a straightjacket. I had no comfort issues at all... I was concerned about the harness digging into my shoulders, but I did not experience that.
