Nice, I SO want to fish New Zealand someday.
Unfortunately(or maybe fortunately) you guys are pretty much on the opposite side of the planet.
We have to work VERY hard to find the kind of fish (based on what I've seen and am told) that you guys can more or less expect.
I'm usually fishing a 6126 with a 480 grain Skagit Compact and ten feet of either T-17 or T-14. I'm usually imparting some kind of motion from a really slow strip of just a few inches to ripping it pretty fast depending on water conditions and temps/time of year.
I rarely just swing but I do if it seems appropriate based on conditions, time of year and all that.
