if I were stringing that racket I would run in the top two crosses before tying off the mains. That way there are no blocked holes at the head. If you tie off the mains at 6H the string going from 6H to 7H holds the tie off sting coming out of 9H off to the side so it's easy to get to 8H for that top cross.
Now there is the issue with the overlapping of strings when you tie off. I the top cross tie off goes under the string from 9H to 7H and when you put it in 7H it goes over the string already in 7H you will have a cross over when you tie it so be careful to make sure the string lay side by side. I don't think it is a big problem but it doesn't look professional.
I have the ability to drive people crazy, not sure if I was born with it or I learned it but I'm damn good at it.
