An amazing video guide has been made by Ghost Zapper over on YouTube.
(Hole time stamps behind spoiler)
A couple of things to note before jumping ahead and trying the holes. I attempted this a fair few times before actually getting it.
I'd suggest NOT
following his Hole 12 and just doing the hole regularly.
Hole 13, same thing, don't follow the video, just play it normally and when you get to the pipe go for around 3.5 bars of power otherwise it will fling you out all sorts of ways
Hole 18, just play normally again. The first time I tried this I got it spot on but the 2nd, 3rd & 4th attempt at this course I couldn't get anywhere near and time ran out. So I opted for the slow play and just played regularly.
Most shot will be pixel perfect so don't expect to be exactly where he is in the video, but you'll 99% of the time be around about. Take your time with the achievements and they will come.
