    Can anyone explain to me what the 'si' and 'Mid size 85' actually means?

    Also when a Pro Staff has ® sybol next to the writing on the shaft is that unusual? What is its significance?

    si stands for Swing speed Index. Players with a slow swing speed play better with a low si racket, on the others, players with high swing speed play better with a high si racket. So advance players usually use high si racquets like the 6.1 or 6.0 pro staff, and beginners use 2.7 or 3.3 si racquets.

    "Mid Size 85" means that the racket head is measured to be 85 square inches. Midsize rackets have racket heads that measure between 80-93 square inches.

    Disregard the "circle r" as an indicator of performance, playability, etc. It is a designation that the associated trademark is registered with the United States Patent and Trademark Office.
