Harbor Freight. The bottom curves inward like a hook so it fits over the board snug and secure. https://www.harborfreight.com/manual-strap-winch-95541.htmlwhere did you get that and is it attached to the deck or something?

I found it interesting how little Ash Kev stretched. Not that I was expecting much but it is indicative that if it isn't prestretched that the slightest bad knot tying, no 10-20% stretch on last mains, anything...will precipitate a large tension drop off the stringer or in the first 24hrs as tension slowly "compacts" that braided Ash Kev. Then there is that first hour or two of hitting that really "seats" the braided Ash Kev. I think maximum prestretch on Ash Kev good, but Zyex, to each their own.
I'm running fullbed Zyex, no prestretch on a number of rackets and like it. Next is Zyex/Origin, Origin/Origin and maybe Kevlar/Origin.
