primary lever length at impact
ive been thinking about the effect of primary lever length at impact, my opinion is that for a swinger maximum power at impact would be the clubshaft and left arm In-line, the butt of the club pointing exactly at the left shoulder. Vs for a hitter this would be less important, more dependent on the thrust against the shaft and the left arm and club shaft being directly in line would be less important. so say at impact one swinger has the left arm and clubshaft in-line exactly vs a player who has the shaft leaning forward outside the left shoulder, who is utilizing the primary lever better? I would think that if it were inline the lever would be longest, but really the length of the left arm and clubshaft are maintained. any thoughts on this? of course this is more tour players concern as most golfers have trouble getting the flat left wrist at all

I don't think so. The farther ahead the hands are at impact, the later the release, and so more head speed, because the max speed is attained shortly after release point and then starts slowing.

I don't have my book with me but I don't think that's quite right my understanding is that once the club starts releasing it reaches maximum speed and maintains that speed trough the interval it does not pick up speed or slow down unless u slow it down by manipulating it.

If that were true, you could just uncock at the very top and wait for the constant maximum speed clubhead to get to the ball.

Bucket .... Where are you good buddy? Give us some "encountering the pulley wheel" stuff Man. Shaft lean and delofting vs max radius.

Who cares how far a guy can hit a mid iron via shaft lean , delofting? What the heck kind of gap control has he got? And how far can he hit a long iron? If its about the same he has a real problem.

no that would just mean the velocity would be less, the sooner you uncock the less velocity per the endless belt. It doesnt change that the given clubhead speed is maintained however early or late it's released. so to me this would say that it it would make a miniscule difference based on the loft of the face and the distance it achieves because of it, like what ob says

I question "more head speed" above , respectfully. More "hand speed" maybe .

The shot may go farther when struck in the above manner for mid to low irons due to delofting. Radius and loft are the factors in distance .... the delofting stops working as you get into into the longer, less lofted clubs.

I'm interested since I'm hitting the ball well now. If I fire my arms to "Both Arms Straight" and get them farther ahead of the ball, shouldn't I enjoy greater distance given a closer right shoulder? But JB says he Swings so my theory is not settled.

That sounds like 4-barrel Hitting - drive the right shoulder partially downplane and then fire the right triceps to uncock the left wrist before CF starts uncocking it. If you fire too late, you'd be a switter, and run outa town like a mangy dog.

I was going to buy a new driver at least but I cannot think of why I should put the Adam Red Line 9.5 with the senior shaft away.

I hit 13/13 drives in Regulation and the avg. was almost 240 yards. Would a "hotter" driver help?

8 GIR, 33 puts - 3 birdies. The Paul Runion putting and putting my chips had me all over the pin so that there was only two 3 putts on "14" stint greens. 5-one putt greens = 2 close chips for gimmies of less than a foot and two 8 footers= and one 40 foot bomb!

My real problem was not believing how solid the Hitting line is so I would fail to take dead aim mostly until the back and then I started pin-hunting. My last 3 nines were 40, 39 and 38.

Impact Fix +RFT + Right shoulder drive to right triceps + Runion techniques = 5 over par! I hit two holes with longish putts that lipped out. Next time-dead aim to the middle of all greens!
