Mark Pearce...Reread-it once was proper English, for the English, not the Americans. Thanks for overcoming your fear of breaking it to me, though.
Garland..."The old Scotsmen were not familiar with your soaring-through-the-sky and putting on glass games that you are referencing." I never reference "putting on glass." I'm not a fan of stimp speeds over 9, let it be known (and let it be known that we could outlaw the stimp meter, too, in order to veil that aspect of the game from the public; most folks enhance the natural speed of their club's greens, anyhow.)
There can be no doubt that the old Scotsmen could tell that the ball they were hitting with that primarily straight-faced club (putter) would roll along the ground and balls struck with the angled clubs would NOT. That part is undeniable; if anyone lofts putts in the air or rolls (not punches, bumps or caroms) shots of any yardage along the ground, anyone has not learned the basic elements of the stroke.
The BP, the HP, any P will not cure putting ailments. Once typical amateurs get going on a good run, they start to think about their score and play defensively. There are no statistics that support an unfair advantage gained by the belly putter. Did anyone see that left to right swinger from the back portion of the 13th green at Sawgrass yesterday, the one that everyone (caddies and pros) continuously under read? Nothing helped that one.
From personal experience, the longer putts with the BP are easily the most challenging; a free-swinging putter helps oodles with that one. I could go on (applause, applause?)
