Can you be in a style stance at the same time as a Rage Power Stance?
Or is a stance a stance and you can only be in one stance at a time regardless of the sources?
But they are both called stances and the initial rules for stances say only one stance at a time. While they should both be allowable the rules are unclear on whether or not they are.
Actually the rules say only one stance of a style feat at a time. The limiting factor would be engaged only if the rage power stance counted as a style feats
