A few years ago, a similar question was posed here and the most common response then was Muzzy's. I was already planning on changing heads and since they were on sale locally, I picked up a pack and found that they flew pretty close to where my FP were hitting. I've had no reason to change since. I am intrigued by what I hear about the slicktricks, but I also hear they're fairly expensive and hard to find. If that improves in the future, I'd be willing to give them a try.
