I tried those the first year they came out. shot several deer with them and the entry and exit hole was very impressive but the blades would fall loose so easy. you have to keep them in the o-ring and if it is cracked or something wrong with it in anyway your blades will come out. to much of a hassle for me so i went back to what i was shooting. the vortex pro extreme 100gr. has 2.5" cutting diamiter. have yet to shot a broadhead that i like as much as them. so good luck with the rages
