fixed blades are the way to go. on a 60lb bow which, judging by your pic is in the 28" draw length? it really isnt all that much kinetic energy to warrant shooting mechanicals. Not saying it didn't malfunction, it definitely should have, but you'll get more efficient shots with fixed blades in my opinion. (I have a smaller frame, not shooting a huge weight or long draw and thus, shoot fixed.) just my .02
