I was fitted a few weeks ago. I am going with the vari-weight, vari-loft was too pricey for me. All I know is that i went from aiming my old ping putter dead left, to aiming inside the hole time and time again. Voodoo, really. Another thing that I found surprising was the difference of the weighting and shaft flex (yes, shaft flex) had on my ability to stop the ball a predetermined distance with alarming consistency. Certainly not a panacea for poor putting, but aiming the putter more accurately gives you a fighting chance at least. The fitting also helped explain why I putt better with certain putters and worse with others. The fitter was not interested in filling me in with the all the details (busy doing his job) so I am not sure of all the ins and outs of it. I learned why I hate any kind of lines on my putters. Beautiful looking putters as well.
