While their at it bring back anchoring the putter. Langer and McCarron figured a way around that one rather quickly and who knows if they're not touching their body with the grip end. Heard on PGA radio they may have lost some players over this rule.
The USGA and R&A should be guided by one objective. Bringing in more players while keeping the one's that you already have. Basically do no harm and banning anchoring did some harm by driving away some golfers. Especially having it legal for 20 plus years.
