FOC increase

[muddyfuzzy]

So the real FOC question, is should I bump my tip weight up to 150? What does that do to speed, would it mess up my spine? So many questions... This would put arrow weight to 485 or so, FOC to 16.5% or so, all out of a PSE Freak with drive cams.

I will look into it for you, we had the spine pretty much perfect on your shaft. If you
could shorten it up about 1/2" you would be good.

I'll get to shoot today and fiddle with Dl, but it like old like the end of my arrow will be right around the Berger hole, so cutting more off is probably out if the question.

Not s great group, but I'm getting it sighted in and used to it. Shoots good, and the arrows were flying great
