Too Be honest, My Deep Purple has gotten better as I have put games on it. It started real early and rolly even after I went to 4000, but as I have gotten 10-12 games on it it has become a better ball, It is a hard arc type motion but it recovers from anywhere for me. I absolutely love it, if you look at my first post when I got it, I said I didnt think I would like it, but it has completely changed my mind over the last few weeks. I did shoot 705 first night out in league after i changed the surface, then backed it up with a 693....both nights I fought the third game and should have shot 750+ if I would have put it away and balled down. Last night I shot 233, 231 and then put it away.
It hits and carries like a truck and it has garnered a lot of attention in my league the last few weeks because of the way it hits and its very consistent in its look. It never looks jumpy, it just looks strong....I do stress it needs oil in the front of the lane....if not it will burn up quickly.....
