Why do you ignore good advice and keep asking about XC type rims. If you are really going to be doing 10' drops, you NEED an indestructable rim. Even then, you'll taco it if you land wrong.
If 10' drops are in your immediate future, get either some ATOM LAB TRAILPIMPS, MAVIC D321's, SunRigle DoubleWide's, or Intense Mag30's,....etc.
If you're just going to be doing a lot of XC type riding, with an occasional 1' to 2' drops(not much bigger), then any XC rim should be able to hold up to "Occassional" drops if you're smooth.
