my 200mm full-face organic helix clutch handles the 160ftlb 160bhp on track no prob at all nowadays, and that's only using 50% of the surface cos my flywheel was machined concave.
so 150ftlb should be a pieceapizz.
the ceramic paddles are a very hard tough material so will hardly wear but it will indeed chew through the softer steel flywheel/PP especially when it's abused on a drag strip or track

suppose the paddle arrangement promotes a harder high-pressure bite but during traffic jams it tends to shudder/chatter during slippage.
I used to have a thin ultra-light JUN flywheel and although it reduced the time for the rpm to blip during heel toe and for the rpm to drop fast during up shifts, it had a very limited heat-soak, heat-sink capacity. so coupled with a small-area paddle clutch it was more likely to overheat quickly and glaze permanently under intense stress.
with the 8kg stock flywheel here I just get used to waiting for the fly to gradually slow down during upshifting.
