I just picked up a total nv, I was wondering how I could drill it.  I am a full roller, so I don't have to many options.  I usually try and go with the Morich drilling, but if the topweight is too much, then it requires a lot of work to make the ball legal/within standards again.  Also, if I go with the conventional full roller drilling(pin down and to the left of the thumb), does anybody know what kind of reaction this will give me?
