A little late to the discussion, but I have the 2 weight Nano Helix rod.
I love it! It is a really nice rod to use and I have had fish to around 4lbs on it with little problem.
I made it for Bugging for Grayling when the rivers are low and clear and the flies scaled down a bit, but it now comes trout fishing with me more often than not.
If you are planning on using heavy jigs and 3 to3.5mm tungsten beads, then look at the 4 weight, but for French nymphing, 2mm beads and clear water, it is lovely.
