225- Since you asked this question in our Hammer forum, go with a Purple Vibe, or a Pure Hammer Burgundy. These will be your best choices, hands down. Drill this with a 5 or 6" pin, and polish the ball, you will LOVE the ball roll!
As for the question about a high performance core in a plastic ball....I suggested this to Ron Hickland at one point a few yrs back, and he told me why it will never be produced. Basically, the high perf block will result in the ball attempting to make a strong move at the break point, but (because ball reaction is about 80% surface) the ball will NEVER react because it is a plastic shell. This type of core costs a lot to produce, nobody would pay for it because it is simply a plastic ball. This is the explanation I was given by Mr. Ron. With regards to the same type of weight block in a Urethane, I cannot answer that, I suppose it would be a much better fit than a plastic shell, but I dont have the engineering degree, so I cannot answer.
P.S. The No Mercy is INSANE!!!
