Crossfires are pretty low profile heads, so they should not be a problem, but they do have little tabs at the back of the blades that are designed to spin the head to the right. If you are using left helical or offset fletching, it may cause a problem. I personally use Slick Tricks, and they fly very well, right with my field points out to 40 yards. Mechanicals are fine too, but it sounds like the tune is off just a bit.
You make sense. In mentioning trying heavier BH's, 125's, I was wondering if adding some weight, such as suggested in the Easton Tuning guide would help straighten BH's out?
I have been shooting the easton's with the fletchings that came on them when I bought a half dozen to try. They are offset some. I figured give them a whirl with the fletchings that came on them, before refletching with something else, adn after they were apparently flying and hitting well, I figured why change?
