Yes, I tend to agree. The sweet spot felt a little smaller than usual but as you said, it could make me a better player given that I would have to focus a little more on hitting quality shots. So, perhaps with a lower tension, I'll gain a little more of a sweet spot. Another thing that I noticed was that the weight of the racket was lighter as well which could be due to the thinness of the 62. I'm thinking of trying the 67 version to give some weight back to the racket. I'm still experimenting....FYI, I normally play with BG-80 at 26.5 x 28.5.
