Last and only time ive snapped braid it was 4lb fireline and i had cast a lure into a tree with no leader ( lure straight to braid ), it was quite difficult and sounded like a thunder clap ( massive shock backlash too ) so im quite suprised to hear of your symptoms.
I get some line slip fishing 6lb vanish on my 4lb fireline, no slip on my 20lb penn leader and 12lb fireline... not as stealthy though, I would reccomend Suffix or Fireline for quality. ( not quantity )
On another note tell your brother well done with the golden, ive heard Gunners has been firing for months, gotta go take my yak out there!
