Ruddbow, It is not that I hate carbons, they just never worked out for me. The three types I tried were Beman ICS, Stingers, and carbon express. I like to be able to tune my broadheads and lost that ability with the epoxy in inserts. I really questioned eithers durability. If it hits hard enough to bend an aluminum, the carbon will come apart, usually. Penetration seem slim with carbons. I found that they hit a target hard and were hard to pull out but shot nearly a dozen does with carbons with a 30% pass thru rate. My aluminums and 40 plus deer have about an 85-90% pass thru rate. I think the energy I get from the aluminums exceedes those of carbons although the physics equation KE=1/2MXVXV may prove me wrong. I guess what it all boils down to, in the last 20 years of bowhunting, I have used aluminums with very few problems and the times I have tried the carbons, I have had some problems that has made it hard for me to place my confidence in them. They have to be good in a lot of things about carbons because knowledgeable archers like yourself and many others on this site use them exclusivly and have awesome success.......
