Interesting... Well I have only 21 dives in my Stiletto. I'm curious to know how much weight you use as I haven't noticed any turtling tendencies of this BCD. I've tried 2x2kg front and 2x1kg front and 2x1kg back. Most of those dives were done while doing u/w photography on a week liveaboard trip which involved getting into sideways positions with both hands on the camera and other odd positions to get a decent shot. In fact there were a number of sunburst shots (shooting up at the surface)where I would intentionally turtle myself and never felt like I was just getting flopped onto my back. It was a very fluid movement from horizontal face down to face up, take the shot, and roll back to a face down position. (it does help to get your trim and weights dialed in as I'm dealing with very little air in the wing) Second I've haven't noticed any riding up, in fact that's what I love about the stiletto. Its nice and snug and sits just above my hip (which resuls in absolutely no noticeable tank movement). But then I've got a little beer gut that naturally prevents it from sliding up
(maybe too many san miguels and bintangs)... Dunno if it would ride up if you're a beanpole. Another thing is with the stiletto I was able to drop 2kg that I would need in my old Tusa jacket BCD. Only small complaint I have is the pockets are bit on the small side, but then if they were bigger it wouldn't be as streamlined. End result is I've just played around with relocating things on the outside (torches) and cutting a slate down in size to fit inside the pocket. I should note that my rather large 6' SMB fits in the pocket.
Since I've switched to the stiletto, I've seen a dramatic improvement in my buoyancy control - being able to get down low horizontally to the bottom to get a close macro shot, etc. Since I've never tried any other back inflate BCD's, I can't positively says this is 100% attributable to the Stiletto...
Thumbs up for packing a Stiletto for traveling when space is tight and I find it very comfortable lying on my back on the surface with it or doing a backwards surface swim back to the boat.
Edit: just noticed the original reviewer/poster is from the pacific northwest (using a drysuit?) whereas I am doing strictly tropical diving in a 2mm shorty or 3/2mm full wetsuit. Never dove a drysuit but I wonder if that may contribute to a less snug fit around the waist.
