Nothing profound as far as technique goes. The Cleveland rep that was present did make one comment that caught my attention. He basically implied that because equipment manufacturers can continue to manufacture clubs with grooves under the current groove rules through 2011, that they will use 2010 to produce (a large number of) clubs that can be sold through 2024 when all golfers must finally adopt clubs with the new grooves. This made me wonder if other manufacturers will be producing vast quantities of equipment in 2010 under the current rules and continue to sell (which is ok under the rules) this equipment to dealers over the next few years.
