Worth noting for the example Monk / Witch combination, the traits you have for your Living Hair that you don't have for Wolf Jaw is disarm and trip, and as both disarm and trip don't care for your damage, you could flavor it as you hitting things with your hair but Really doing a Wolf Jaw attack, and then when you want to trip people you're Really doing a Living Hair attack. As Wolf Stance doesn't say you have to do Wolf Jaw attacks (vs e.g. crane stance, which say you have to do crane stance attacks), you can do Wolf Jaw when that's reasonable (damage) and Living Hair when that's reasonable (tripping, disarming).
