I’ve got 2 Wilson pro staff 6.1 classics – I’ve had them for a year. One is in good condition with slight ware from getting low balls on the forehand side. The other one I dropped while serving and it has light cracks. I’ve restrung this racquet a few times and I’ve been using it as my first racquet to minimize the ware on the other one – so far it seems fine. It would defiantly work as a spare. I just bought a Head Liquidmetal Instinct and would love to get a second one. If any one has got one that they want to trade, please let me know. I’d be willing to cover postage as I live in Australia.
