I have been working with the speedchain for a couple of weeks. You can really feel the lag.
What is the speedchain?
Numbersguy,
I have always felt the good lag is a product of proper alignments. Float loading on the downswing will increase accumulator lag but educated hands controling a good pivot will aligned the club and body in a powerful lag position before impact. Apply the Star Triad to the Three Zones of Chapter 9 and you will produce "impact envy" in your foursome.
