I just bought one of these off of ebay, the specs are 15 lb 3 oz, 3-4 pin, 2 1/4 top.....I am always looking to replace my tour menace which has about a 2-3 inch pin drilled directly below the ring finger with the cg in line with the thumb. I get a nice even strong arc reaction and plenty of hit...Any ideas on how to drill this to be similair to my tour menace?
