I've been using a TM R7 with a ProLaunch blue, reg flex, pured shaft for years. After several knee operations and a bad shoulder / rotator cuff, I couldn't get any distance with it. My drives were down to 200 yds (on a good one). Bought this Bio flex with the senior shaft and tried it today. It was set for 11.5 deg and that's where I left it. I hit 13 out of 14 fairways today with the shortest drive at 195 (it was the one that missed the fairway in the woods) and the longest at 245. Most were in the 225 - 230 yards range. As soon as the wrench arrives I'll try other settings because these drives were very high and I wasn't getting a lot of roll. Looks like the R7 is retired.
