904 or 727 ?

I can only speak from personal experience, my 1st 904 was so destroyed inside I couldn't identify what was the root cause of it's demise.(:burnout: too many burnouts??)The sprag (among everything else) was chewed to bits. The 2nd one was an obvious failure where the ring spun in the case & cracked it pretty good. There weren't many(if any) performance parts available for the 904 back then so the 727 was my only real option. Now with the increased popularity of the 904s & my own experiences I would opt for a new sprag if I was building one now. That's just me.
