As someone who has been a high level athlete (Olympic hopeful in 1992) and coach, I have always credited my coaches as performance does not happen in a vacuum. Instead of 5%, I’ll give you “missing link” credit. While about 5% in volume, its value is much more.
This might be the first time I have ever recorded my swing in landscape mode on my phone. I should probably record all my FO swings like this so the clubhead isn't cut off.
Love this drill. I do it a lot in practice. It's kind of my "B" swing when I'm out on the course and not striking the ball well.
What does this have to do with anything? We're not talking about a 80g xxx stiff shaft and a head 4* of loft here. Read up on what the golf ball offers; it's not about swing speed.
No. It's about flight preference. A harder ball gives you more ball speed. Who doesn't want that? Nowadays, both the v and the x are very similar in terms of ball speed, but spin and feel are a little different. Nonetheless, the idea that swing speed determines the ball is nonsense. It's about achieving the launch characteristics that fit what you want. A slower speed player with higher spin loft can benefit from the reduction in spin. Also, a faster speed player with lower spin loft may want a spinnier ball (Tiger's ball is VERY spinny).
It's about the individual, not some overbroad generalization.
