Question about tempo and swing speed: My SS on mid and long irons seems OK given my age and lower back pain (high 70s, tops out at 82), but my driver swing speed is only a few mph higher. While demoing a 3W I mentioned it to the fitter (a PGA teaching pro) who suggested it might be a tempo issue. I know from using a Zepp analyzer that my tempo is pretty inconsistent, but even when it is pretty smooth (2.9:1 or 3:1), I rarely reach 90 and usually more in the mid-80s. I am working on tempo with the Zepp and a golf metronome.
Is there anything else I could be doing to pick up a little more swing speed on the driver?
Thanks for any insights.
