Just got a '12 Cannondale Flash Alloy 2 29er with the "Lefty" fork a few weeks ago and I wanna hit some trails.

As a kid I had a GT Pro Performer and jumped it quite a bit off some fairly nice jumps. I don't know if things have changed but could I still jump a hardtail? How much "air" could I safely manage without damaging a frame and/or myself? I'm sure weight is a factor and I weigh about 210 lbs.

Also, when jumping, how do I want to land? Do I want to land fairly flat or would I want my rear wheel making contact with the ground first? I used to land with the rear wheel first but that was on a BMX/Freestyle bike without a fork with travel. I'm assuming things are probably a little different with a fork that travels?
