I have used alum. for years and two years ago I got a new bow and tried the carbon arrows it went from 250 FPS up to 272 FPS I was impressed enought that I got 6 The thing I like I went from a 3 pin site to 2 pins and feel good about it. My deer last season was 35yrds and the first pin was right on he went 70yrds and folded up. the arrow had no damage on it and I can use it again even though it did not pass through and it banged off the brush that he went through and he uplled it out 10 yrds from where he went down.
