Hi Marlin-Mike,
All the keen jiggers choose coloured braid because it makes it so much easier to work your lure in the right zone. Re. brands, all jap braids are top, but since you're thinking of using 80lbs (personally I use 40lbs Varivas), you'll have a comfortable safety margin and you can use any brand (except wiplash, it's crap).
NB: Dyneema or Spectra is the (manufacturer) name of the fibre used to make super-lines. If the fibres are weaved, then it's called braid (eg. Bionic) and if the fibres are fused then it's gsp (eg. Fireline). PE is just a rating scale invented by the japs (eg. PE5 = 5*10lbs= 50lbs, etc.)
Hope that helps!
