Welcome to the board. I definetly agree with you on the sparring aspect of BJJ. Because there isn't any striking for the most part, you can have a pretty good workout without getting pummeled.
As for schools in the Seattle area, there are 3 that I know of. There's a Ralph Gracie Associate in Burien (
www.ralphgracie.com), supposedly a Morreria Associate somewhere in Seattle, and a Carlson Gracie affiliate in Tacoma which will probably closest to you. I've taken classes at the Carlson Gracie affiliate (
www.seattlejiu-jitsu.com). The teacher (Professor Marcelo Alonso) is pretty cool and the emphasis is on tournament BJJ.
So that helps !!
