People who like to see that flippy backend reaction will really like the Fringe.  Those who like a strong backend but smooth, readable reaction will like the Manic.

I'm not the biggest fan of the color combos, but it's better than the Frantic for me :-)  It's a good thing the balls are good...

Thanks!
If you were happy with the Frantic, you'll probably like either ball.  Of course the Fringe will be a bit flippier than the Frantic.
The Fringe is about 2 feet longer than the Manic, but it shouldn't be more than a foot longer than the Frantic since they're both 1500-grit polished out of box.  The Fringe will just be a bit more aggressive off the dry.
Talk with your ball driller to get the reaction you're looking for and maintain predictability as much as possible.
