Sorry let's try this again. What I meant to say is that the 18 mm knuckle position will often take regulation specs to very do places. In this case a very long dip ie..425 & short blow 1 1/2 inches. The rest ...what David said. Dale Or the regulation Dale David Love wrote Moving the knuckle (better to have bought the shank with the correct knuckle to begin with) to 17 mm and taking 1 gram off the hammer you will achieve approximately the same goal as moving the knuckle to 18 mm (maybe a little better in fact). ************************************** See what's free at http://www.aol.com. -------------- next part -------------- An HTML attachment was scrubbed...
