Who said anything about top pros, Michael? Even most of the lowly local pros don't need your magic putters.
:doh:
Open/Top/Bottom/Round/Square whatever you want to call them.
Its my understanding a lot of open players don't even throw putters off the tee and prefer mids so really makes sense too being driving putters are not something every player experiments with as much as "putting" putters.
Not to mention you couldn't turn one of those open players off their KC aviar if you handed them a 24k gold disc... stuck in the old ways of new days.
