I have been diving with the Diva for almost 2 years, and absolutely loved it...until I tried on the DivaLux! That one is sweet! A little more money, but its definitely worth it! The backpak padding and sports bra insert are made of a sturdier material..almost like leather (ooohhh...a "kinky" BC!), plus the pockets are huge now, with a little zipper one on the cummerbund. It has 2 tank bands (complete with the non-dumpable trim weight pouches on the bottom band)and it has a combination of jacket inflation and back inflation. I think the one I tried on was size small, and it had 34lbs of lift. I'm not sure on the lift of the other sizes, but I assume it goes up with each size. Haven't had a chance to take it out for a test dive...but I will next weekend! I'll let you know what I think.
