Honestly, it looks like I'm in the minority here, but I couldn't get them to fly out of my Vectrix XL last year. It was shooting bullet holes through paper. I guess it must have been a fluke but I was really pumped about using them, but after beating my head against a wall for a few weeks I gave up. Now I'm shooting Tekan II's and Rage's. I'll probably play with some Slick Tricks this year as well.
