I would have thought if you strung the Instinct with 2 pieces it would have been faster. Something tells me you are stringing the racket bottom up for the cross when you do one piece. If I were doing one piece I would use an ATW pattern but I do not think that would be faster than two piece.
When you're dead you don't know you're dead. It's the same way when you're stupid.
