Personally, I carry thunderhead 100's. I have not had the opportunity to shoot anything with them yet. A friend did have one shatter when it hit bone in a deer. He switched to Muzzy's after that. My thunderheads fly the same as my field points. I will probably use them until I have a bad exerience (if I do have one). When/if I change, I am going to try the Slick Tricks. There are just too many other things to spend money on right now.
