dampening for offroad rides

I commute 90% of the time on road and have a road set of wheels and set my suspension hard for road use, when i pt the dirties back on i set them soft again. Last ride i did alot of small jumps and the front bottomed out. what do you do to your suspension before you ride harder offroad?

went for a ride sunday with the suspension set stiff and its much better, could do with a little less compression dampening but overall confidence inspiring
