What pressures are any one setting around 12 stone?

Depends on the bike. Leverage ratios, travel and all that.

13 stone, meta sx, 260lbs

Vague question is vague.

If it helps, I’ve been running 185psi on the float x ctd on my Dune, I’m 87ISH KG (not sure what that is in stone). Was running higher, 190 is as wa’s going through all the travel, just added a bigger volume spacer and 185 seems but right now, although got to give it more of a thrashing yet to really test it.

Hope thus helps….
