When I got on a launch monitor about six weeks ago, I was measured at around 88 mph with my normal swing. When I really tried to hammer it - I never got above 95 mph.
On the other hand, I hit close to 300 yards several times over the past weekend - playing on well-marked courses and hitting 520 yard par 5's in two. If the scorecard is accurate, there is no denying I hit some drives of that length with that swing speed. I know it doesn't square with what the calculations say but I hit that distance all the same - on a few occasions. I think it is the combo of my 10.5 degree clubface and the ProLaunch shaft...and very dry fairways due to a prolonged drought.
I hit holes 7 and 11 in two shots and was about 210 out on each approach in..Playing from the III tees.
