Nowadays, it's rather expensive to demo racquets. Most local tennis shops do not have a broad array of racquets on hand. My tennis club doesn't have the Tour 90 or Tour 95. They have the head heavy tweeners in the Wilson line but no player's racquets. Many of the shops have gone to a $5 per day per racquet charge. Then there the problem of the grip sizes and foremost, the syn gut that most demo's are strung with. Buying a used racquet, restringing it with your string may be the most economical and realistic way to demo a racquet. If you don't like it, you can sell it on these boards. New racquets are usually backordered for demo at TW. Head has a good demo program for ranked juniors where you can purchase any racquet they make for $75, up to 2 racquets a year. Now that's what I call a righteous demo program!
