A friend of mine swears by their stonefly nymph on a trout magnet jig head under a TM float,

I've never used them, don't know that I've ever seen a Nikko soft bait, but wondered if someone here used them and wanted to share their experiences, like how they rigged them and how they fished them.

I use their “Sashi” for micro fishing, but that’s it. Wish I could help more.

The guy on "Creek Fishing Adventures" uses the Nikko helgrammite and some of their other baits a lot. Pretty good videos IMO.

I use the one that looks like a wax worm, put it on a trout magnet jighead. Works well for rainbows
