How much kroot in auxiliary cadre

Currently I don’t own any kroot but I want to play the auxiliary cadre. My question is how many/ what kinds of kroot is a good mix for that, was thinking of three units of hounds, a unit of six rampages, one unit of farstalkers, one unit of carnivores, a farstalker, and two units of vespid. This comes out to around 800 pts but I’m looking for a second set of eyes to see if this is a good amount.
