Re: grip question
JMHO knuckles and thumbs and such are OK indicators of your grip. But you can grip the club poorly, twist your hands into position and have what looks like a good grip.
I think it was Sam Snead (maybe not) that Harvey Pennick told the story about that went like this.
The amateur asked the pro (Snead?) if he could see the calluses on his hands. The pro said he didn't have any calluses, although he obviously had hit a ton of balls over the decades. Pennick went on to say that blisters and calluses come from putting your hands on the grip and then twisting them into what looked like a good position. He said to get your hands in the right position the first time.
I am no expert obviously as my handicap will show.
I've just really been thinking about the grip a lot lately. The feeling of a good grip is a lot like casting an open faced fishing reel. I bass fish in a lot of ponds where the moss is so thick you can only use a plastic worm with no weights or sinkers. To really throw that extra light bait out there you need to have fluid wrists, and not try to over power your cast. The only way I've been able to do this is by holding the rod loosely in my throwing hand in my fingers. It's a finesse thing more than a power thing. That same feeling reminds me of a good golf grip.
