This might work for you, but I have found the 80s are worth the money for the points. It's also mental.. which most of this game is!I just shoot 77s across the course. At my level (expert) it’s just not worth the hassle of keeping track of two different boxes of ammo. The 80s aren’t that much better.
Not a huge X count but I was pretty happy with it, considering the circumstances that day. 80 SMKs.
