Now that's the kind of information I'm interested in.
I actually got a friend to record my swing and it confirmed what my golf partners have been saying. My tempo is very smooth. As regards my left wrist, flat is definitely not the description. Some work required here.
I hit some different flex shafts today and found the S300's to be the most comfortable and workable.
I have been offered a set of nike vr pro blades for €300 ($385, £240) and can get a third off for trading in the Callaways. Have to say I'm very tempted. Loved the control I had with them.
