I did notice on OW 2 that some of the water on the near side of the island is in bounds. So if I'm not close enough to run it, or in a conservative mood, I just aim on the short side. It's been working. Going for eagle hasn't paid off too much so far.
One general trick on OW is that the bushes don't seem to affect putts much (or maybe that's just a 926 thing in general?) and tree trunks (as urdizzle mentions in his videos) affect flight whereas tree branches tend not to MOST of the time. The putting in bushes helps out a lot on that 2nd hole island bush as well as that bush on the RHFH uphill shot with the death putt.
With all the ratings talk: do holes always have the same ratings? Or are they rated easier with some winds and harder with others? Also, on multiplayer rounds, do we know if we all have the same wind? I've always assumed so, but maybe not.
