Shorter cranks are better where clearance through turns is an issue. Downhiller and duel slalom riders use 160 - 165 mm. A lot of North Shore Freeriders use them as well.
Longer cranks will give you more leverage and torque. Many single speed bikes have longer cranks to help during tough climbs. I've seen a guy using 185mm on his 1-speed.
If you've got a long inseam, they will also suit you better. If you're doing a lot of XC riding, you should go with either the 175 or the 180 mm.
For a mtn bike, most come standard with 175mm and so you'll find that size more readily available in shops and on-line.
