Buddy of mine shot a 300 last night with the Dare Devil! In the Baltimore area, those Optimus balls sold like hotcakes! They could not keep them on the shelves, there was always a backorder!
In the Riverdale, MD area, closer to DC, not so much! Sporadic sales here and there. Those folks I've seen throw it, threw it well! I always wanted one but didn't pony up and buy one.
It will be very interesting to see how this "TRICK" rolls. I love the Dare Devil motion.
