[quote]Just to cover some more bases:

1. What is the draw-weight range of your bow and what draw-weight do you have the bow set at?
2. Have you had string/cables replaced lately?
3. What is the total grain weight of your shafts?
4. How are your groups when shooting?

I was just thinking the same thing myself.I was out shooting my carbons last night with no problems at all and decided to shoot some of my alluminums just for the heck of it.My 2 friends were there and they couldent believe how quiet my bow was with the xx78.I am shooting the patriot and might decide to stick with the alluminums this year.
