There is that. I'll probably will go for the Kabs because I'm going to use the kit's Dark Lance for a kitbashed Death Jester.
Oh, with Kabs, make sure you give two of them the special weapons such as the Blaster, Splinter Cannon or Dark Lance. Some factions are packing serious armour and firepower, and they'll even the odds. If not going with Wyches then definitely tool up the Sybarite with a blast pistol and agoniser/powersword.
In a nutshell, an all splinter rile team is not recommended!
