My main goal for 2010 is to really work on my back hand, I have never really been able to get it down. I recently have added a Z Comet, and a X Comet to my bag, and I feel like it has helped me to shave off more strokes than any other disc that I have tried. I think that I even like it better than the Buzz. Although, the Buzz still isn't coming out of my bag.
Just looking to see what other people think about the Comet, So far 2 weeks in my bag and I love it.
