Clutching for Propane

So I just picked up a 11' Propane M8 and may need a little help with the clutching. It worked awesome on my first ride but my primary was always ridiculously hot, like burn your hand much before the secondary. It ran 8050 RPMs. The clutching is a bit unknown since it started with a OVS torsional setup and was switched, or partially switched to a Mountain Magic setup

Anyway, here's the stats, as well as I know. I'm running 10 lbs at 7500-10,000 ft.

Weights: D&D heavy hitters at 72.3 grams
Primary spring: It's black with a greenish blue strip (this may be a Speedwerx "Blue" spring since that's what OVS puts on these things.

Helix: straight 46
secondary spring: orange

72gr pretty light for 10 psi try around 80gr ,.slipping makes heat. not sure on the blue spring but try something with a finish rate around 290-300. I use a team 158-290 works for me. not sure on the profile on the heavy hitters, I use D&D mag weights loaded to about 85gr at 11-12 psi. now you can see how much weight these things can pull . power is power mines a gasser though.

a straight 46 might be a little steep ,I'm using a bdx 46-36p holds 8300 like a freight train very consistent.
