People say Sergio has lots of Lag. That's Accumulator #2 Lag they are usually referring to. The angle between left arm and clubshaft is what they see.

But TGMers know that Clubhead Lag is the resistance of the Sweetspot to change direction, which is established during Start Down. It is very slight, very ellusive and hard to see.

But it's not hard to see in this case!



Now THAT'S Clubhead Lag!

You may say he's using some women's whippy shaft. Uhh....no. It's XXX

Nice pic there Tong...Bobby was the one that got me started in TGM - despite those cheesy ads from OHP.

Per 6-C-2-A "The Clubshaft is stressed by the weight of the Clubhead resisting a change in its direction or velocity - which is Acceleration....Change of direction bends it during Longitudinal Acceleration (10-19-C)..."

Per 6-C-2-C "The prestressed Clubshaft will resist the added weight of the ball during Impact..."

1/16 inch of bend adds 1 ounce of mass.

Per 2-M-1 "Power is the total effective force impinged on the ball."

Per 2-C-0 "The Ball leaves the Clubface with force proportional to the compression produced by Impact."

Power is 1/2 x Mass x Velocity squared.

When you load the shaft, mass is added.
When mass is increased, power is increased.
When power is increased, the "total effective force impinged on the ball" increases, the FURTHER the ball flies if all things remain the same.
