For me it was learning to 'let go' of the handlebars a bit. Keeping a loose grip on the bars (while still maintaining control) let a lot of the vibration dissipate before it rattled your bones. Also on techy stuff I tend to work the bike more, like the others have said. A lot of weighting/unweighting to smooth out impacts and a lot more 'mini hops' to clear roots and rocks that you might have let a front suspension fork absorb. You will learn to pick great lines too. Well, great if you have no suspension.

Stick a nice big tire up front also and run it soft. with that 1x1 you should be able to fit a big one. It will provide a little cushion if run at a lower that normal pressure.

Have a Blast man!
