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
