Lots of questions and I don't have time to answer all of them now.

I ran your bow real quick yesterday and the arrows you have show that they spine well with 125 grn tips and 28 inches. That is all the farther I got though. The Maxima's were good as well, and to be honest probably better arrows, just lighter. If anything both arrows are a tadd stiff, which is not always bad, too weak is bad.

I think spine on arrows is measured at either 28 or 29 inches, I don't remember which. Not full length though. And the program takes that into account anyway. You need roughly a .400 spine if I remember correctly.

I forget what the aluminums were, I think 2117's? I will play with it more later. Today is my day off, but I have lots to do. (should be doing it now)

I just liked the way the cybertech shot and felt in my hands is all. 6 3/4 is not that short of a brace height either, 7 is considered good. Really depends on your form.

I will get back to you later.
