i was the last one of my buddy's to starting using mechanicals, just started past season, and got the reaper razortips, recommended by many, they flew great for me and left awesome blood trails, everyone i know uses grim reaper razortips, nobody really uses the razorcut that i know of, my proshop guy, tries a different head each year and hes stuck on the reapers, he said they are the best head he has used yet
