Store where I work, it is the best selling frame. As for Wilson's plans on the whole "SET", they will be launching several frames by the end of the year with the same engineering (ie, 16X15,etc). On another note,,, I'm still using mine. Find it very hard to put down and begin playing again with my other frames. Last week I hit with a friend whom I haven't hit with since before I began using this frame. At the end of our hit, he said, "I don't recall you ever hitting with as much spin as you hit with today."
