Double Battalion or a Battalion and Patrol?

I don't really think any of our three subfactions are bad at filling out battalions, our troops and characters are generally fairly cheap. The only main issue is you often don't want too many of our characters since you can only make so many good combat or buff characters, and I would add that for cults it's probably a bit more expensive to fill out a battalion since I'll happily run 5 man warrior and wrack units, but I'd much rather have 10 strong wych units for the extra wych cult weapon.
