I use metal idle screws and spring in my 35's, always stay where I put them. The lighter springs are nice as well. Also use the longer adjusters up on the caps, for all of it is a few extra bux, so why not!
I use all of this...just think Jason, now you WILL call Jeff again right now and get them hahaha.
