I have purchased 3 types of braided line to try.
1.10 - Braded Kevlar String Utility Cord Mason Line for Kite Bridle Fishing Camping Packing Creative Projects (150lb)
1.30 - Black Braided Kevlar String (9KM) 8 strands (300lb)
1.40 - Dorisea Extreme Braid 100% Pe Black Braided Fishing Line 16 strands (400lb)
The 1.10 looks thin and not as many braids or as
@graycrait mentioned more twisted (could be good as a cross string)
The 1.30 and 1.40 look promising. (to be used as a main or cross)
On my stringer I did do a test pull and it seemed to grab and hold the string.
The biggest challenge is to figure out a way to thread through the grommets with the ends being too flimsy
I will try
@treo and
@esgee48 suggestion of using nail polish or super/crazy glue on the ends.
I will post my results when I do.
Here is a link to my pics of the line & stringer
