Ball park G-Ball focal lengths

Ball park G-Ball focal lengths

I've looked far and wide for an answer to this, and have yet not found one.

I'm simply looking for ball-park focal lengths with the G-Ball installed for the NUBM06, NUBM07, and NUBM08.

Looking specifically for one which has smallest diode image (that is to say, least rectangular) at somewhere between 30mm and 130mm.

I have already had good success using an NUBM44 and M140 with a G2 lens and I would like to find out if using the G-Ball is good enough instead. It would be tons more convenient if the G-Ball would work.
