I just got two Ridiculous Asym's and love them both! The first one I had drilled 35x4.25x30 and it has great early to mid lane roll with continuous back end. Typically when I have this reaction I can't follow the oil inside as it breaks down. With this ball I can follow the shot in. So far I have gone as far as fifth arrow with it and had great reaction and carry still. This is great for short oil patterns, house shots, and several sport patterns. My second Asym I had drilled 45x5x70. This ball goes longer of course and believe it or not has a stronger back end shape as well. I have a Guru Supreme drilled almost identical 45x4x70 which lays off at the back end like I want. I figured the Asym would go longer but still kind of lay off on the back end. This doesn't overreact but has a nice continual motion that on my first practice session with the ball I shot 299 with. (I threw it a bit hard, ten pin). This layout is very forgiving by not over-hooking too badly when you get it right a bit early and it still makes a nice tip when you miss left. What more can you ask for? These are definitely my go to balls!
