I can't speak to the other brands of drysuit and eVent is supposed to be the cat's pjs but I was able to pick up a GMER for 7 hundo from NRS during a sale and I am sooooo glad I did.
The Rocker fullface is bomber. Spendy, yes, but it's your domepiece, bro!
Astral stuff is shweet, too. I have my eye on that green vest that somebody just said isn't coming out
. Oh well, just saved $200.
I have the Xtract and it's a good vest, just doesn't have very great coverage on the back and no it doesn't have a plastic spine piece. That was the "Hairfish" that Stohlquist used to sell designed by Ed Lucero. They don't sell it anymore.
