I don’t think it would be that hard. I’m an 11.8 index(right now), which makes me a 14 on my home course(6175yds/131slope). I tend to shoot better on shorter courses. Our flight will have our handicaps at 13,12,13,13 I have no doubt that I can shoot 85 or under. Will I? probably not, but I don’t think it is preposterous or that odds shattering that it is done.
