Have you thought at all about a 5-pack? RFX front with 5-spot rear that can be bought at any Turner dealer. Personally, I’d be a bit nervous dirt jumping a just barely sub 6 lb full suspension frame, even occasionally. Body weight would probably play a role though, and I’d likely case it half the time. I personally now like 6x6 bikes for XC/trail riding, especially down in Moab. Of course, Wasatch trails are super tame, so 5” is plenty. I know one Maggette using an AS-X as a XC/trailbike, so I don’t think I can ever whine about bike weight again.
