I tried the CT's when they first came out. They fly very nice and really do cut a nice channel into targets (never was able to connect on a critter with it). The downside I noticed it that because they do cut a spiral channel, pulling them out of targets is very difficult and ofter will rip out the blades. If you shoot hay bails you can just push it through the other side and you should be okay though. Overall I thought they were a very nice head.
