I'm 73 and an 8 handicap. I have used the titleist 917 d3 driver since it was first released. My swing speed has slowed down and I now average only 200 yard carry. I am very consistent with the d3 and usually hit the sweet spot. I have tried the new ts1 and ts2 drivers, but I get about the same carry as the 917 d3 and less consistency. Thinking about trying the ts4 or tsi4 drivers. Any one have any advice. Please don't tell me to go get fit. I live in the country and the local salesmen know less about fitting than I do.
