1) Big tires and low pressure. I run 32c tires.

2) Specilaized Bar Phat (the thin ones) or similar

3) Off the Front Grip Shapes... I use 6.. I put one so the heel of my hand is supported in the drops. And I create a nice wide and flat area where the bar curves. Takes a while to get it right, but it helps.

4) Double gel tape (but not with Bar Phat, too bulky). I love Cinelli Gel tape but the price is insane now.

5) A light bar, my Ritchey Biomax has some give to it, which means it should absorb a little of the shock.
