Fortunately, I did not spend years beating this, only minutes. However, the several minutes I got with this level featured some of the best hole logic I have seen in a while!
Somewhere along the 60th try I accidentally slipped my finger, doing something I didn't mean to do. And it just so happened to be the right idea, once I thought about it...kinda ashamed of hitting upon the big trick accidentally, but I'll take it. 64 tries, over the years :-)
