I'm faced with a bit of a conundrum here. I've been offered a trade of a Nanoray Z-Speed for my Nanospeed 8000 1st gen. I'm not sure which way to go as the Z-Speed is newer thus probably a little more popular while the Nanospeed is more of a collectors item or something for the enthusiasts. Both rackets are in mint/scratchless condition. Looking for your thoughts and thanks in advance!
