if i take an impulse zone and drilled it the same as the red zone, what type of difference would there be. PAP is 5 3/4" and 1/2" up. layout on the red zone is pin above ring finger...4 1/2" to PAP, psa 1 1/2" right of thumb. i was thinking of having the IZ drilled to check up early and continue in the backend. something like a 4" pin to pap, next to ring finger which would put the psa 2" right of thumb in the 5oclock position. any thoughts & info?
