I am not arguing the math. Head rotation thru impact area and the amount of weight to increase or delay same doesn't take all that much. A slight delay is all that is needed. Same with front to back sliding weights to influence L/A. It's the degree of influence that determines the amount of weight.
And that other guy you mentioned isn't he the advocate of shorter is better and yet now that theory is out the window as it's all about 2" overlength wedges on Sl irons? Just sayin.
