how many of you run them and for those that have, have you ever broken the rivets on the spool? if so was it difficult?

reason I ask is so far I've broken 2 that were supposedly good for alot more power than I'm making. I'm thinking my 3rd clutch(different company) is going to do the same thing. it's starting to rattle very loudly like the TOB but sometimes I can feel it in the clutch pedal if I press it just right. it also goes away when I push in the pedal and sometimes if I pump it the rattle will stop. I'm thinking it is b/c the spool has worked itself backwords to a stuck position. pics of carnage below.
