dude, if the choices were 6k and 10k, there might be a big enough difference to give a non-hating response. but seriously your talking like arctic white compared to faint bluish... there is not much of a difference at all. if you like a bluish appearance go 8, if you want the best possible lighting of the road, 6k is probably for you, after all, its not just about spending money to look cool, they actually do provide better lighting
