Ric,
It really depends upon your friend's speed, but here are a few choices that can work pretty well on medium to drier shots.
Blade Pearl (Best med-dry lane ball I've ever thrown)
Green Gargoyle (You'll have a hard time finding more backend than this)
Eraser Boost (Some very light shine might be needed)
Wicked
Erase-It
Angle Evolution Extra
There are certainly others, but I've seen this group do bad, bad things on the shot you're describing. Hope it helps.

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
