Had the el hosels for awhile many years ago. They go away. (And without buying any Tin Cup inspired contraptions!)
Great point; try to hit one.
Took a lesson to get rid of them. The pro finally just walked away & said they will go away ,& they did.
Cost a lot of money in bets before they did!
My 66 had 2 eagles, one from about 70 feet & one from about 8 inches, 4 birds & 2 doubles.
Never to happen again.
As far as the putting goes, it will come back again ( hopefully ).
As you know, once you start making a few 6-8 footers you will make more of them.
Still the most frustrating but rewarding game around.
Good luck.
