both used. ISO swing power 900 SS G4.5 , few chips with BG65 @ 23lbs. 90$ CAD code 13079 Carbonex 20 G4, few chips with BG70 @ 20lbs 80$ CAD code 4 037SP (old code)
sorry, I am not interested trading. I am not sure if it is a SP code, but it said made in Japan on the shaft.
The 13079 is the old serial system, which means the racket was made before year 2000. Do you recall where you purchased this from? It definately wasn't in Canada because Canada did not carry G4.5 (unless it was accidental shipment). Determining if it is an SP was simply looking for the SP at the end of the racket's name. Since I have a 900 SP (old and new serial), the model appears on the shaft as "Isometric Swing Power 900 Long SP".
