I had my putter fitted for me through the Taylor Made performance lab. I definitely noticed that there was a increase in distance control, mainly because they discovered that I needed a little less loft on the face due to keeping my hands behind the ball. As a result of this, I was able to see, through super slow motion cameras, the ball take a big hop at impact and two smaller bounces before the ball started rolling. After the subtle adjustment, the ball took a much smaller hop and then started rolling much faster, this made it easier to control how far it went, especially on longer putts where I had to hit the ball a bit harder. A good way to see this is if you go to the practice green when there is still dew on it, hit a couple of putts and look at the water trail and see how far the ball goes before it starts rolling.

So I guess to answer the question, yes I believe that a putter fitting is beneficial. I agree with BigViv, any club that is fitted to you will have a performance advantage over a club that is not fitted for you (assuming you are not one of the straight OTR guys).
