This guy is wired for speed. I'd bet you he can beat most guys in a foot race too.

BTW big clubhead yes but he hits the SS on a super long-shafted driver.

At his level I am sure he could do OK with persimmon.

I am surprised no one has brought up Mike Austin.

...

BTW again.........if you really want to see the goods you need to see his face-on:

You are a perfect example of what golf club marketing has done to people. There is only 1 exact "sweetspot" on a club PERIOD.

Now what has changed through driver and even iron technology is the forgiveness on OFF-sweetspot hits. That has improved where as with a persimmon driver maybe you would lose (throwing out hypothetical numbers for an example) 5mph of ball speed for a 1/2" miss of the sweetspot and with today's driver heads you migh only lose 3mph of ball speed.

But don't be fooled; there is only 1 sweetspot on the head and that spot isn't always in the center; most of the times it is closer to the heel which is why a lot of iron heads these days are being designed with toe weights and shorter hosels to try and move the sweetspot to be more in line with the center of the face.

Assuming a 205mph ball speed and perfecto contact; you are looking at 136.6mph of swing speed. However this isn't realistic; more than likely the contact is more at the 1.475 rangish which is a figure i have come up after lots of research to be a more realistic number of efficienct contact and you get a swing speed of 138.9mph.

But that realistic number is based more on shorter 45" drivers and very good players who aren't swinging completely "all out." So i would tend to lower that smash factor for a long driver to maybe 1.45. Using that you end up with 141.3mph of clubhead speed for a 205mph ballspeed of a long driver using a much longer shaft and also the effect of going "all out" on every swing.

you are the perfect example of a golf contrarian. how are you defining the "exact sweetspot"? how about the gear effect and the spring of metal faces vs wood?

I am not an engineer so i can't pretend to explain it correctly; yes the COR effect has increased from wood to titantium; however that doesn't mean the sweetspot has increased in size. The bigger sweetspot is a marketing gimick to define a lower loss of ball speed for off sweetspot hits as i have already explained.

Let me state for the record; sweetspot sizes haven't increased however the forgiveness of off-sweetspot hits have.

Thus you are penalized LESS for off-sweetspot hits with todays equiptment than you would be with older equiptment.

1.50
1.49
1.49

Smash Factors above; i'm guessing these are their "longest hits" and not their average. Mighty impressive to be basically at PERFECT CONTACT at 130-140mph of swing speed.

I believe Zuback did a exhibition thing earlier this season on TV with Bubba and others. He ended up hitting i think a 400 yard drive on a par 5 right in the fairway. Then skulled his sand wedge over the green.
