When I worked in a pro-shop in Sweden we strung an awful large amount of rackets each day. One of the young guns at that place strung one POG 14/18 racket at 7 min 38 sek with me holding the stop-watch in my hand.
It was unreal to see! It was strung with a prince synth gut on a Neos 1000 machine.
No Guts, No Glory
