So....how much time to you spend above 6400 rpm? That's the only time a 17% SC pulley is going to spin the SC any faster than a 15% pulley at peak rpms.

Awesome! Finally some real world numbers. I haven't seen these before. I hardly ever go above 6k myself, so looks like I'll be going with a 17%..
