There's nothing evil or inherently destructive about "crit as you go" -- the Scribblies did it for years -- but it really does not sound right for you. Or maybe it would be if you found people who write as quickly as you do, but I'm dubious.

In my experience it's awfully hard to find a bunch of like-minded people to critique with, and I feel my successes in this area have had more to do with luck than planning.

I wish you lots of luck.
