Don't know why but couldn't edit my other post so here's how it is done. I run into this a lot when I string Prince rackets with Kevlar mains. Here you are tying the string from 10H to 8H.
Before pulling tension on the 7th main put the pathfinder in 8H from the inside of the frame. After stringing the outside main put the tip in the pathfinder awl and pull it through. To use the starting clamp pre-weave the two outside mains and place the tail into the tie off hole. Ten use the starting clamp as a bridge to tension the 7th then 8th main before tying off.
Everyone has the right to be stupid... it's just that some people abuse the privilege
