I know that when doing cross that is in between the two last mains ,you do not alternate. eg on my 6.1 95 16x18 , one side is over over over under over.under over....under under under. Why do we have to do this. How different would the string play if we dont do this, and alternate every crosses? I ask this question is because i have few friends that just bought their own stringing machine, and i see that all made the mistakes of alternating every cross. And when i told them that they are wrong, they asked me why, and i was like eh...........idk.:?
