I had 1 racquet professionally strung out of this reel. I will mail the remaining reel to the Buyer; which is 660'ft minus the 40'ft for that one string job. I love this string! I hit a much heavier ball during demo. The only problem was: the 17 gauge killed my serve! The thinner string bit the ball entirely too much for me. I'm not advanced enough to fix it. Gotta go back to 16 gauge. Happy Bidding! Or "But it Now!"
