he i'm shootin 275 fps and i shoot muzzy broadheads, they don't fly no diff than a mechanical as long as you get the blades lined up with the fletchings, to do this on an aluminum arrow, heat the shaft right at the insert and use the wrench to turn the broadhead, to do this on a carbon, heat the broadhead not the shaft and turn the broadhead so it lines up with the fletchings. The guy who tunes my bow for me told me this, he was taught how to tune a PSE by one of the company's really high up person, VP or something like that.

As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them.
