Cam mod for XC?

[harescrambles]

Right now i have the cam mod done to my yfz, but i have heard that it's better to not have it done for harscrambles.
If you were me and race xc what would you do?

i think its the best thing you can do. plus its free.people will try to tell you it take power from the bottom end but it does not it just give you a little more top end.

Thanks for the reply.
Right now I've got it apart doing the valve adjustment so i thought i would be a good time to change it back, but first i wanted some advice from xc riders. i kinda think it gives me an advantage on the hole shot and i don't want to lose that to gain more lugging in the woods
