Jeff; One was made from 7X tippet rated at 3.1 lbs. w/tippet ring. It broke around 8.5 lbs. One made from 6X tippet rated at 4 lbs. w/Shorb loop went to over 13 lbs. with out braking. Another one was 4 lb. test mono with a Shorb loop that went over 12 lb. without breaking. Have to do some more testing for sure.
