RE: switching from alum to carbons
Reddawg, what type of difference are you looking for?
1) Speed
2) Stiffness
3) Kinetic Energy
4) Trajectory
5) Durability
????
You'll gain some speed depending on the weight of the carbon you selected, definately a stiffer arrow. Your KE will remain the same providing you didn't change the draw weight/length of the bow, trajectory will change marginally and the durability is defined by the abuse you put an arrow thru...if it's in a target, carbons wear more than aluminum, they break but more difficult than aluminum.
Basically a little speed is gained but makes marginal changes to a setup/sight.
