Of all the bonuses, I think either XP bonuses and chance of an additional skill are out of place or that should be the benefit to a complete set. I think there's definitely going to end up with some popular bonuses and some unpopular bonuses. It seems difficult to support all of the themes equally.
I didn't memorize them, but things like bonus Axe damage wasn't going to entice me. Rifles/Revolvers bonus probably wouldn't either.
