We fish Stockton beach during the salmon run and we often have to cast long
disances. What I do is fish with the lightest line capable of landing my
intended species in a reasonable time (in this case 8lb) and I platt a
double onto the main line about 1 1/2 rod lengths then to the double I tie
on a 50lb shock leader also about 1 1/2 rod lengths long. This allows me to
throw an 85 grm Halco about 150 metres (wind behind me) with a 13 foot rod
and spinning real.
If i swap to bait I just rig the sinker onto the shock leader above the
swivel and use a "Vanish" trace to the hooks. I've never had bust off's and
the combination of the double and shock leader makes it easy to trace and
land fish.
