I was looking at a Volkl DNX 4 (not my own). I noticed there were two crosses on the outside of the frame that are not in the usual location. Form H12 on the crosses it jumps to H14, then comes back on H13 then jumps again to H15, then continues its sucessive crosses. Until it reaches T16 where it does a similar skip and double back. T16 to T14, then T13 to T12. I've never seen this type of pattern before, but it seems to be at the ends of the DNX bumpers on the side of the racquet. Is this the way Volkl's are supposed to be strung?
