Been lurking on this forum for a few months along with the yellow book in hand. In spite of playing the game for a fair amount of time at a reasonable level(~1 hdcp), I'm amazed at how much I don't know about the golf swing - mine in particular
.
One thing I was experimenting with this last weekend was the feel of extensor action. There've been some excellent posts about this, but I'm not sure I have the right feel for it especially in regards to PP#1. It seems to me that with a 10-2-B grip and applying extensor action that the PP#1 is felt under the right thumb pad pressing down on the left thumb at somewhere between 12 and 1 o'clock on the grip. With a 10-2-D grip, it seems like the PP#1 "moves" to more of a feeling of the cup (or heel) of the right hand pressing on the left thumb at almost 3 o'clock. Not sure if this makes any sense at all, but these feels seem to stabilize the Power Package during the swing. I haven't noted a discussion of PP#1 changing based on grip so I'm thinking maybe I'm still in the dense fog.
So - when applying extensor action is there a very specific location of PP#1 on the heel of the right hand or can it vary depending on grip type? There's a decent chance I have this extensor thing all wrong.
I'm still flip-flopping between 10-2-B and 10-2-D for my own swing(swinger not a hitter), and there seems to be advantages to both but that's a whole other discussion.
