Me, I'm a BIG buy, so there aren't that may choices - I believe Mustang does make stuff for us oversized guys
RE which PFD. While I personally like a nice vest type (vs one of those univeral life jackets), I'll say floation devices are a LOT like flastlights and knives in the best is the one you'll wear. Is inflaitible as good as a nice SOLAS rated jacket/vest/drysuit. No, of course not. On the other hand, if you're willing to wear and inflaitible all the time, every time, it's a heck of a lot better than the best sitting in the bottom of the boat
In another thread, I mentioned that my daughter (now 11) has been invited to do some sailing next summer. I WILL go buy her the best vest I can. Well worth the $$$
Disclaimer - I'm one who worries a bit around H20. I'm on the Shelter Island Ferry, and feel nervious because I'm not wearing a vest, or have one at immediate hand. First time I ever go on, I checked where they store their PFDs
