Powdercoated mine twice now and they've not cracked, strong wheel IMO. Proven last year with my "little" misshap, so those that have cracked must have really gone through some real stress.
If I went the MO route again, then I would deffo like some 9x18 6 spokes, they look pornographic! But I only want 9's on the back if I can source 2 RL7's in that width.
Only pic I can find...
