because of my bad shoulder and the pain i get just from drawing and shooting a bow , i now at age 69 i have been using a Ravin R-10 X-bow so i have been using Sevr and Swackers both have worked fine . i wanna get a lower poundage X-bow and go back to using Zwickey Eskimo`s and a cut off 22-19 aluminum shafts because i have close to 100 of these old broadheads and shafts. good luck ,Pete53
