833 hold up to 500hp RB

I'm just a streeter, and I really like my Centerforce pp. I did not like the CFII disc,(it was way too hard on parts), and I swapped it out pretty quick, for a full organic.I solved the Electric sw on/off type engagement by shimming the pp off the flywheel some. Yes the flyweights sometimes stick at low rpm, but a quick neutral-blip usually clears 'em up.I like a little slip below 2800.It's nicer in traffic, where I spend a lot of time.It's dead smooth once the fly-weights are moving, and has hung together for 10 or more years.
The discs I have been using,on the otherhand,do not last very long,usually spitting out the springs.
I shift at up to 7200 pretty regularly, in my 367 cuber.
Yeah I'm older(62) but certainly not feeble.I prefer the diaphragm for it's ease of modulation.
I got no bad comments about the CF pp.
