I have bowhunting for 42 years I went to carbons when they frist came out afcs and bemen and so on. I have never look back. I still shot xx75,xx78 and x7 inside for target line cutters, but carbons for 3ds and out side target. Hunting I still to this day can't get over the way they preform in the field hunting. I never have had one brake in the bow not even the older ones. make sure you check them when you hit some thing hard grab the arrow on both ends and turn it and if it's soft don't shoot it. I have been shooting pass throughs on deer and Elk and pulling the arrow out of the ground for year's now, which I wasn't getting that all the time with xx75 and xx78 's. there have been year I have shot as many as 3 deer with the same carbon arrow. there has been times I have used The same arrows for two years of hunting with is very good for me because I shoot a lot of trees, rocks, bottles and things out stump shooting.
