I'm also running the SPX. I really like it, especially the "hole shot". Don't forget to add a few teeth to the pinion when you first start to run. Keep an eye on the temps after your runs to help get the gearing right. The Novak 21.5 will have a temp range for you to shoot for.

I'll see you at MSI when you get there.
