Gnolls have great flavor but rules wise they are boring and seam a bit weak for their CR.
They are mean to be kind of scary for my level 1 PCs but if I compare them to my PCs they worse in almost every way except HP.
I was thinking that gnarled Kuru warrior 1 armed with a long spear.
I was thinking of going with a simple weapon focus for the feat.

Both a gnoll and a kuru with 1 level in warrior would actually be CR 1/3 (-1 non-player class, -1 slow wealth).
Heres the gnoll race: http://www.d20pfsrd.com/races/other-races/more-races/standard-races-1-10-rp /gnoll-6-rp
They are more than adequate if you want to use them as enemies, there is no reason to switch to kurus from a crunch pov.
