That's like asking who would you rather have in your bed, when they were 25 years old, Marilyn Monroe or Sophia Loren?Mary Ann or Ginger?Jennifer Anniston or a Charlize Theron?
Now this is interesting. If the goal is to increase interest in bowling, why not do a series of matches pitting the best in the game against each other, one on one. Duke against Weber. Williams against Barnes. Rash against Belemonte, etc. These would be fun to watch.
Pete was the best at the "crotch chop" and that is all! The best bowler of all time was Earl Anthony. Walter Ray Williams would be a close second. Unlike PDW both were true gentlemen who respected the game and were an asset to the sport. Bowling would be better off if Weber took up knitting.
