Try circle hooks, you don't need to strike. I love the Mustad Demon in a 4/0 or 6/0. Just tighten up as the fish runs and game on!
if you dont mind me asking what is the reason for the steel trace surly you will get more takes on mono?Clearly the GP mista wiska's are different to their Kzn counterparts.
I use a sliding 1/4 ounce sinker, bead and a steel trace and clip a 4/0 hook onto the trace (will post pic tomorrow). I cast out and give an extra 3-5m slack, once a fish takes the line and the slack, I strike, I have a 99.9% hook up rate on the first run. No 2nd and 3rd runs down here in Kzn.
