Choking Up When gripping the Club

I grip the club at the very end of the handle - and I've known from a long time that most players don't do that. But it was comfortable and my swing worked so I didn't change.

However as a result of another batch of unmentionables I have decided last couple of times out to try gripping down the club a bit - maybe 3/4"-1" of handle showing when previously none was showing - and the difference in the feeling of my address position is huge. Indeed it feels 'right' when for a good number of years it's been feeling a bit 'wrong'. And the result seems to be a more upright stance and swing, and a much better strike. Not difficult given how flat my stance and swing felt and how awful my striking was.

I can't believe that such a small thing can make such a huge change in feeling, but I am going to persevere. Who knows...
