Jeff,

Since you've had pass through problems with both fixed and mech heads I'll just state the obvious. The heads aren't the problem.

Personally, I think youare movingdown the correct path when you decided late this season to go with a heavier arrow. I may get flamed, since there is more than one way to skin a cat and some guys love light arrows, but given the choice between a super fast light arrow and a slower heavy arrow, I'm going to take the slower arrow every time. I don't even bother crunching the numbers for KE anymore. Any modern60 to 70 pound bow and a 450 to 550 grain arrow should blow right through a deer at the distances we hunt these animals. It was true back in the late 80's when compounds were a lot slower and it's true today.

Sometimes I think we get too wrapped up in numbers.When I bumped up my arrow weight again this season, I didn't shoot one single arrow through a chrono. I didn't care what it said.
