I also see TXG Tour Experience Golf have commented on the vid, stating they have also done similar tests and found little difference in launch/spin from shaft changes alone.
I have in rounds we’re just messing around in hit a drive with my driver (G30 with X Stiff low launch/low spin shaft) and then hit my PP’s (female) driver (Wilson ladies driver with ladies shaft and teddy bear grip).
I hit a good one with mine, then put a nice steady swing on the ladies driver. I was 2yrds behind my own club with the ladies driver.
It all comes down the feel.
