idea... you should do a roadshow at big tournaments and such. allow people to come in and see these rackets up close and personal for a fee, whatever you may choose to charge. It would give the spectators a good idea of the heft these pros use and hopefully serve to make fans appreciate the game a bit more. Im sure big tourneys such as Indian Wells would even pay you to come down and exhibit your collection and answer questions for fans waiting to hear the story behind the stick. You could do a lot with these... I actually have connections with the roadshow business and could potentially help you out. Send me a PM and i'll pass over some info.
have a great one
