Looking at the picture, pug, trying to posit what may have caused the cage failure.
Possibly too much clutch bell endplay? Does it look like the inside of the clutchbell was riding on the shoes? A problem I ran into once that was causing frequent engine stall going off throttle. The rollers themselves display either possible skidding on one half of their length, and/or excessive heat (lack of lube?) on the other. Hard to really tell but looks suspicious.
As stated above, were it me, I'd try to stay with the roller for this application. Be interesting to see how you resolve this. 'AC'
