Just a comment:

You might want to measure driver speed as well. Would make it more interesting. I recall seeing Yodasluke swinging (or rather hitting) a dowel by a swing speed radar. He got it to 144 mph or something like that. 10's of mph's faster than the driver.

Also there are two SpeedStiks. As I recall you should use the red one if your body mass is over 160 pounds.

Again: Just a comment.

I'm not sure what the Speed Stik weighs, it might even be more than a driver. It's longer for sure. No comparison to a dowel.

The red weighs more than the blue. At 185lbs, I'm using the red one.
