I went with Woodys 144 template, and 144 Fast Trac Top Gun 2 1.5" stainless studs. 96 studs in double plastic backers, and the other 48 in the new Fast trac Airlite XL (extra large) round backers made for the longer studs. I've used TGII's for four years and haven't lost one yet (knock on wood). Great product. I like the Woody's pattern too...it kept me from worrying about tunnel damage..was easy to use and got exact placement of the studs...important with the FC tunnel.
