Pin in the thumb is another one of those layouts that is very dependent on the customer's specs. The flare is going to be reversed, moving toward the thumb and away from the fingers, like a full roller layout. For a high tilt, low track customer that will probably be OK, and if his PAP is located 3 - 4" away from the thumb hole it might be a good layout. For a customer with low tilt and a PAP 5 1/2" over and 1 1/2" up it will likely be a disaster. -- JohnP
