Bumping this thread up to post the results of my install for forum posterity.

I installed an M50 JB Racing single mass aluminum flywheel (JB 520-020-228) on my M44 Ti using a solid hub M50 228mm clutch kit.

Install went smooth except I mentally blew it and ordered stock length flywheel bolts which are grossly too long for a JB Racing aluminum flywheel.
Other than having to go get the right flywheel bolts that it was a pretty easy install.
I took the opportunity to replace every single shifter part in the car starting from the trans backward as well.
I use an old oddball UUC solid stalk race shifter stick in a body mounted solid shifter cup from one of my E30 M3 race cars. Shifter feel is awesome now.

Driving impressions are stellar.
It feels like the car gained 20hp. I know it didn't gain 20 HP,,, but the spin up difference is pretty amazing.
The car feels night and day quicker than it used to and thats with me having 2.79 rear gears.

No noise, no chatter, no shudder and it pulls away from a stop as well or better than it did with the stock heavy ass dual mass setup, idles like stock.
I can't find a downside yet.

Now its got a 228mm 6 cylinder clutch which should last forever, the whole new clutch / flywheel assembly is lighter than just the stock flywheel and the car runs so much better.

Can anyone tell my why Hans and Franz used those heavy ass dual mass clutch setups in these cars?
Much like the COP vs. the stupid M44 coil packs with plug wires,,, the decisions that were made on these cars design confounds me.

So if anyone is contemplating switching to a 228mm JB Racing setup, highly recommended. Really makes the M44 wake up.
