What ever putter you decide on, have it fitted to your stroke. Economical, or expensive, either one will perfrorm quite well for you if fitted properly to your stroke. I have read that a properly fitted putter will save a 10 handicapper between 2, and 4 strokes a round, if they are using a non fitted off the rack model, and switch to a fitted model.

After a proper fitting, the trick then becomes finding a ball that feels good to putt with, which will compliment your putter, and your stroke. GJS
