I sure don't disagree with Dr Tutelman. I think we're more in concert than not in this case.
I mentioned the butt end only as a last resort. I don't nor did it recommend it. What I hoped to demonstrate was that no matter what one does re; swingweight, a change of a point of so is essentially meaningless. Bobby Jones may have been able to spot a single SW point difference but I'd suggest that the overwhelming majority of golfers can't tell the difference from a couple of points or more. What do we hear often? "Wow, you can sure feel the head, it must be perfect!". I heard that very thing today when I let a guy swing a 3 metal I own. If a shaft is 60 inches long and the SW changes a point or two it sure feels different, but on a relatively firm, 38" shaft with a rubber grip on the end? Excuse me, but if you say you can feel it, you're fulla . . . well.
