Hey Geoff,
It all depends what sort of structure is arounmd and in most case yesterday none... but we were not to happy of the tghough of flattys eating out $20 lures all the time so we opted for 6lb and normally i would use 2lb crystal but at this time 4lb flouro green was 12 buks cheaper than 2lb crystal so i just used 4lb flouro fireline ey and leader if i knew i was fishing arond pontoon on surface normal 6lb mono .. ckear mono would do it,
Hope this helped Geoff
