hi fellow hackers, this is the first i herd of the double overlap or interlock but i can see how in might help with getting more lag and not let a person get so wristy in there swing. i know im gonna give it a try to see what happens.what works for one might not work for the other. all ya have to do is have a basic good swing, if ya find some thing that works for you go with it. look at tommy 2 gloves on big break i think his knuckles on right hand face the target (hahahahahaha) but he can hit the ball great. ps i hope he wins he seems like the only one with the confidence to do it.
