Depends on how much you wanna spend
From Kona, Scott, Giant make some good stuff.
Why XC do you like dressing up in lycra?? Why not Dual Slalom...now thats fun. Hucking jumps and racing real hard. Now you need a different frame. Like K2 flying monkey or Azonic...To bad all the tracks here are wet.
I have decided to live forever or die in the attempt
