But not some random guy at the range? Good, I'll cling fast to my social anxiety and continue to not talk to strangers while hoping he gets his kid a lesson or two.
The father's golfing was fine, but he wasn't teaching his son any fundamentals. The poor child had the club gripped like he was going to beat someone with a stick, swung with all his weight, kept his arms bent, and had the clubhead well past his hands at "impact". Father's response was to have him tee it up higher and mentioned something about a wrist.
Every time I see this, I am reminded of when I was at the range with my dad and I was slicing every shot. His response was "my instructor told me to pull my right leg back when that happens, so try that". Possibly sound advice, but being told how to hold the club and to stop swinging outside-in with an open face would have helped me fix my swing problems early on instead of compensating for defects that were otherwise curable.
That's the issue. No basic grip was taught and I saw a whole lot more frustration than fun. But I may have been projecting. I saw a father who enjoys golf enough that he wants to share it with his son, but a son who could learn to hate the sport because he has no foundation to build upon.
Anyway, ranting done.
So basically, you probably would be better off trying to track down the Exotics adapter... Just a footnote, @Hacker James the hilarious thing is on the Tour Edge store they have EX10, EX9, E8 and XCG6 adaptors. I didn't see any 7s but that doesn't mean you can't get one.
