No, but I got some advice from a friend who is a pro. When I got fitted for irons everything was bog standard (shaft length, lie angle etc), and I know my swing isn't consistent anyway. My driver swing speed is around 90mph (had lessons last year and still have a note of some of the data) so he recommended I went for a regular flex shaft. I hit 9 drives with it on Saturday, all of them good strikes and 6 of them found the fairway. 2 were slightly left and 1 sliced but was in play. The pick of the bunch was on the last, around 255 yards leaving me a wedge into the green which for once I flushed, setting me up for a 10 footer for birdie which I holed.
