Of course either way can be done…
a gravity drop is simply a feeling of passivity at transition… this can be done with ease by initiating transition with proper application of the lower body, mainly knee flex…
Dropping the club “flat” and few do this better than Robbo… of course can be a passive act.
I have also seen some good players drive it down very actively with the arms packing in, and not initiated as much with the lower body.
But here is the deal…
If you have the hand action at the bottom, and proper ground pressures that create a solid resistant platform for post impact pivot acceleration…THEN you would be doing yourself a huge favor to get the golf club coming from as low, flat, and behind you as possible.
Once you fully understand the advantages of flat entry into impact from P3 along the 4:30 line, and the advantages of setting up your gear in your favor, you create a significant geometric advantage over golfers that don’t. Then that geometry really sets you up for applying the forces and physics of the golf swing in the same way that Hogan, and Trevino, and Knudson, and Player did, as they were all obviously all over it.
Traditional thinking suggests everyone has a lie angle to set their clubs based upon their height and arm length… you go in, swing on the mat, get fitted, pay your money and walk out the door with that perfectly matched set as Tom Wishon and others preach… but this is very limited tunnel vision thinking.
I am 6 feet tall, played most of my career off standard lie angles, and I fought the dreaded “long and left” pull shot my whole career. The weak right shot I used to hit was often a bailout move to avoid long and left. I have my irons now 6 degrees flat… and I could not imagine going back to more upright clubs.
I had always wanted to flatten our my swing, and to do this, you also need to flatter out your gear, or you are missing the point. It’s really the flat gear you want, not the flat swing. The gear sets up your golf swing. I wish one of these so called brilliant teachers I had years ago would have told me this… I’d be typing these words from my hill top Malibu mansion.
Now I can release the club as hard as I want actively with the hands, and the ball is not going left. Nothing helps you make good contact better than a bit of aggression through impact… and knowing you can really go at it without the fear of long and left is gold dust.
If you think about it… an over the green or even back left on the green leaves you typically a down hill, big left to right putt, chip or pitch shot. That is why I really stress my students to get their gear set up correctly right through the set…
This stuff is nothing new…
Trevino in his book talked about how he was able to beat Nicklaus, because Jack had his wedges way to upright, and Trevino would just kill him inside 120 yards all day long. Jack was usually putting down hill with a left to right putt, while Trevino was up the hill right to left and closer.
Hackers fight the slice because of their horrible golf swings… and pro shops sell them crap gear compensate.
On this site, there has not been one student yet that has not learned to draw or even hook the ball by the time they are done with module #1 and #2.
Then we can set up their gear correctly for a proper release… then everything else is just refining the golf swing, and tightening up tolerance standards.
