how about an aggressively drilled barbed wire? i have one drilled weak for extremely dry lanes, and i still carry out the corners. it has a less aggressive cover, but it will still give you the backend(if they are as clean as you say they are) if you have an aggressive drilling. i had one drilled for my dad a few months ago(he likes to play the outside without swinging it too much, opposite from what i like to play), aggressive drilling, and it slid right through the heads into a very controlled arc into the pocket. it wont snap at all, but it will definitely generate power through the pins.
