Some fine points that I've learned to encourage and maintain Clubhead Lag through the Impact Interval. CL has almost nothing to do with speed. Acceleration only needs to apply a greater force than the strength of the shaft and the weight of Clubhead inertia. And, Stiff shafts bend easily. Stiffer is better. Stiff shafts stay with you.

1. Don't create more Lag than you're prepared to Sustain (need for the length of shot)
2. The Right Forearm must be Driven through Release and Impact
3. The Right Forearm Flying Wedge must remain Intact. The Right Forearm Flying Wedge Alignment is what brings Clubhead Lag into Impact. Without the Alignment, no amount of Thrust will help. Clubhead Lag is "Keyed into" the Right Arm Flying Wedge Alignment at "Startdown".
4. The Right Elbow must Straighten as the RFFW approaches the Angle of Approach for Impact. It's easy to lose Clubhead Lag when the Hands Slow. If you can't maintain Hand Acceleration, then use a smaller Pulley. That's what it's there for.
5. The #3 Pressure Point is indispensable from start to finish. "Trace and Drag".

If you can learn to sustain Tip Bend on a fishing pole, then you can learn to sustain Clubhead Lag with a Golf Club.
