I'd sooner ride my 6.3 full than my 4.3 full.
That says a lot.
My suspension is revalved and resprung though. I'm 200ish without gear. I could stand to have a bit firmer springs both front and rear when loaded down. Problem is I do a varying degree of riding from trail days with no load to full on trip with 70lbs of gear.
