gzg is on the right track, but I'm gonna start simpler than that. If your slick tricks aren't grouping w/ your field points.....We need to just start over. The flight characteristics of the ST's are so good, you honestly shouldn't need to move anything, especially that much.

I see you are shooting 500 spine arrows, and your draw is pretty short.....Depending on how long those arrows are, they may be underspined @ 60#'s.......In fact, I would suspect at 60 #'s, unless they are like 24" long, they are underspined. I'm gonna head on over to easton's website and research that a little....Add that 100 grain point on there, and it makes them weaker still, than say a 75 grain head...

Have you papertuned the bow with fieldpoints?

Here's why I say what I do.....last year I shot slick tricks, out of a perfectly tuned bow @ nearly 320 fps....I screwed them on and shot them, they flew perfect. Hit right w/ my FP's.....You really should be able to do the same, and when things are off this much, sometimes it's best to just start over from scratch. Start w/ the basics......First let's find out how those arrows are....then we'll go from there.....
