Funny you should ask. I was at the tournament in Scottsdale yesterday and was watching Jan warm up with his doubles partner Travis Parrott (watch out for this guy in the future!). I started talking to his stringer who was going to string Jan's racket and he handed it to me. Long a Prince man, I knew immediately that it was a Prince Thunderbolt, painted EXACTLY like (I believe) the More Power. When people say these are "paint jobs", they are professional paint jobs so good that you have to look real close to see a difference. Quite enlightening.
BTW---Gambill looked good in his win last night over Brendan Evans and his hair is brown now, not blond.
