That's the skinny of it, sand circle, glue, shape, shoot!:thumbup:
I switched from the Tiger Sniper to these to try as I heard they were harder and easier to install. I didn't see that, but maybe it's because my bad shot stroke is more liken to a break stroke, medical reasons..They tended to start mushrooming, so bad in fact I cut them off and replaced them..What I did do next before I re-installed the new ones was pressed them in my tip press for a few days which is in my 12 ton press...After that I installed them and they are killer! I think somewhere after that I read that the Sniper was indeed harder by a little then the Onyx, next time I may just go back the the Sniper....Save some time and a few bucks..
