I do not really get choosing the line on the breaking strain. I would have thought diameter would play a much greater role… I have line with the same diameter but vastly different breaking strains. For a extreme example, 6lb Maxima Ultragreen has a diameter of .22mm, compare that with Stroft GTM 11.2lb line which also has a claimed diameter of .22mm , Same line thickness for nearly twice the breaking strain! Now marketing departments seem to make up the numbers a bit, so the true diameter/Breaking Strain might differ.
Just something to think about….
I fish braid when spin fishing, and normally use a meter or two of 1X or 2X tippet material, which depending on the spool/brand I grab has a breaking strain of around 8-10lb.
