I find the show "entertaining" but the way they do some of the evaluations can be of, ummm, questionable validity. Often it's just how good the person doing the testing is with the item in question. If you gave me the newest and baddest set of clubs on the market and put me up against a PGA player with something from the 70's from some garage sale TDW results would indicate that the 70's clubs were better than the new ones since "they" performed better.
It's a fun show (to me anyway) but nothing anyone should take too seriously.
