Re: Shaft PUREing, Puring, or SpiningConterversial topic, it's tough to say.
There's definately something to it that's physically demonstrable. In my experience, certain shaft companies tend to have "less" of a spine than others.
However, the only place you're going to be able to truly visualize puring benefits is on a frequency meter, and you don't play golf on a frequency meter.
In the end, a good swing with an unpured shaft and a good swing with a pured shaft yield the same results for me. I wouldn't pay more than $10 to have a shaft pured, personally. But the most important piece of equipment is between your ears, so if puring gives you piece of mind, by all means do it.
