Good mellow proactive ball, but the core just isn't enough.
Best bet: wait until hammer puts a Syntactive Cover around their Violet Offset Hammer core. That one will be a sure thing.
It also doesn't seem to matter how the ball is drilled...unless the outsides are considerably dry, you will NOT get any type of movement worth talking about from this ball. The Jackhammer core is jsut not enough to make it a good match for the Syn Sledge. I suppose if it were shined, it might make a good medium-dry ball, but I have yet to see anyone try it. Wish I had more good to say about this ball, but I just don't.
