I figured most of the 80th would have a few kills in it. Maybe some just haven't logged the time in the last month.
Without looking at stats, the only 80th members that I can think of off the top of my head that spend a good deal of their P-38 sorties in the G would be myself, Corkyjr, Pawz who's a relatively recent convert, and probably Cactus.
I would guess most fly the J, but we have more than a couple L fans as well.
