Comming back to 4 barrel: have you tried it?
Do you feel it difficult to do?
If the gain was so little as stated by Homer why Ted (the Hitter's poster's boy) would be using it instead of 3 barrel?
My intuition is that maybe it is easier to do as it seems and maybe the rewards are greater than Homer thought?
I don't know if Homer could see the future of golf equipment and golf courses. We've played courses in our Section events as long as 7800 yards. I know that the equipment has changed dramatically, but 6800 yards was long at one time. In our world, having distance is a great asset. I've got a course within miles of my house that's close to 8000 yards. There are three fairways that are unreachable, with a north-easterly wind. It's awesome for a masochist like me. I'd use six barrels if I had them.
In the audio from the Master's classes, Homer spoke more than once about the Swinger's Start Down being advantageous for both Swingers and Hitters.
In my own stroke, I love to feel the additional stretching of the right triceps (bending of the arm) in the Start Down, before the shortening of the triceps (straightening of the arm) in Release. It feels to me like a Major League pitcher. There's an obvious Pivot. Then there's a blast off of the Right Arm.
I like to use this analogy:
(If you've tried this, you might be a red-neck)
Someone standing on the hood of a stationary car can only jump so far.
Someone jumping from the hood of a moving car can jump farther.
The car could stop accelerating and the person could fly off.
The car can accelerate so fast the person becomes stuck to the windshield.
