One of these? A BT ball fitter goes up to 6" and your span went past that!!!!!!!! Somebody is looking at something wrong or you have monster big hands.
To double check your span.
With your thumb inserted in the thumb hole and laying your fingers across the holes and your hand relaxed, the half way point between the first and second joint should be at the gripping edge of the hole. If your using inserts it's the gripping edge of the insert not the drilled hole.
See at the 17:45min. mark in the below video.
Just to double check,
With your fingers laying across the holes, hold the ball like your going to roll it. So that it settles into your hand, then without moving your hand.
Example:
Rotate the ball back up so you can see where the edge of the holes are in relation to the midpoint between the two joints. (or get a picture form below like this one.)
