I think it was mentioned in the R2 coverage at DeLa and somewhere in the tourney thread - yeah, that place has some 5' gaps and you're throwing at a wall of trees hoping to get through. But if it wasn't part skill, why are the same guys on the top cards all the time, even on those "gimmicky" courses?
How small of a gap/line does it have to be for you to consider it "no true line exists"? I'm curious what everybody's thoughts are on this. How tight of a gap is OK? Is that for a gap between trees 100' off the tee, 200' off the tee, a tunnel shot width, multiple gaps at a wall of trees?
I remember watching a video of a course and I believe it was in Texas for a big tournament. A lot of the holes were under 300 feet with no true line and it was poke and hope. The pros doing the commentary even mention that during the video.
I'll try and do some youtube investigation.
