I really like my magnum pro forks on my stache. Don’t find them harsh at all…. Pretty sensitive to setup though Alex and you must make sure you let the air out, flip bike upside down and pull up to extend the forks fully before pumping air in. Initially I lost about 10mm travel too but then I was pumping up with weight of the bike on the front end (negative chamber is primed in position unlike the rock shoxs that have a bleed through port)
I also needed to run relatively low pressure… About 20psi less than what it says on the leg for my weight and run more (3 click) of compression.
Rebound set fast…. Just a couple clicks from fully open.
If you are feeling them harsh also just unscrew the top of the air leg and try removing the air token (just like other forks you can adjust the air chamber volume to make the fork more or less progressive)
Seals also take a while to bed in fully.
Great forks once dialled in. Takes a while to set up properly as you are fighting the undamped squish in the large front wheel!
