One or Two?

We're experimenting again and want to know: Is it more fun to have one large granola bar or two smaller bars in a pack? Happy-Go-Lucky Foods has two sizes of bars: 1 oz and 2 oz. The smaller bars are sold at the farmers market, and the larger ones are for shipping and retail. Someone recently suggested that part of the fun of a Twix or Reese's cup is to have two portions. You could have one to keep and one to share or keep two to to yourself. Tell us what you think!
