Dual disc clutch recommendations?

[69hugger]

It is time to ditch my T-56 trans & LT pull style clutch setup and upgrade to a Magnum and dual disc clutch. This is behind a 502 based big block with a 1 piece main seal. My engine is internally balanced. It has 700 ft/lb. of torque.
Having heard great things, my thought was to use a Centerforce DYAD, but Centerforce tells me they have no flywheel for the 1 piece seal crank that is internally balanced.

The only twin disc setup I have found is a McCleod RST clutch. They can offer either an aluminum (my choice) or steel flywheel. Then there is an adapter ring that bolts to the flywheel to mount the dual disc setup.

I am looking for any experiences with the RST clutch setup, good or bad, or any other options I have missed.

Thanks in advance for any help!!
