Which flywheel with LS7 Clutch?

When I did the MOI calculations, the 9" disc just blew everything else away. Everyone seems to love this thing, and... well, I'm sold.
I looked hard at the McLeod RST, but decided on Monster based on a few reports, and the fact the flywheel is included and the whole assy is balanced.
It's expensive, but I also hope this is the last time I have to even think about the clutch on this car
MOI results for the record
Stock LS6 // 0.146 kg m²
LS7 + RAM Flywheel // 0.172 kg m²
Monster S Twin // 0.135 kg m²
Time to rev ∝ MOI: Twin ~8% faster than stock, 27% faster than LS7

Having some flywheel weight for the occasional drifting but not a lot of it.
The non-organic friction material doesn't dust as bad
And no self adjusters to cause higher rpm issues like the LS6/7 clutches do.
I was REALLY considering a twin disk but the added cost & chatter at idle made me go single.
Gotta rebuild the torque tube and my diff too though 😅
