I've shot them 2x years now, and I won't switch unless they stop making them. I've got them figured out pretty well I think now. I did manage to buy a large package of extra rocket rubber bands towards the middle of season and honestly I can't see myself shooting anything else as long as I have these extra bands for them. They work well without the bands, but that extra band truly makes these heads a better option in my opinion than anything I've ever seen. Iwish I had pics to share of the first 2 bucks I shotwith these heads, the heart pic below is from the first of them,but the entrance hole on both was a realistic 5-6" long.
