I agree with the others. I have head to toe instadry at the moment, and while I am happy overall, I don't think my next suit with be ID. As noted, it is just not as durable as nylon-coated neoprene. It's really nice as far as drying time, however.
I would buy the booties again, despite the separation issue mentioned above, because those tend to stink the most and I think the biggest benefit lies there. My bp/w's 2" crotch strap (with protector from DiveRite) nearly cut through the wetsuit along it's two edges... I had to have a seamstress replace the whole crotch. And yes, the cute little dots fall off and offer little protection. The hood is fine, but it's not nearly as comfortable (read: stretchy) as my Gold Core hood I use with my dry suit, so I would probably go that way next time for the hood, if I weren't planning to get an attached hood next time around. Going separates seemed like a good idea at the time, for flexibility, but anytime you're wearing a 7mm suit, you're wearing a hood, so the only "benefit" is one more thing to carry and a lost ability to pull it back.
Again, the drying time rocks, and there are occasions when I positively gloat about my ID suit. But that convenience comes at a cost. Literally.
