Hi to all,
MrEsox, is this the type of minnows you are talking about.?
Kaufmann Janssen's Minnow
Hardyreels, that is the exact experience I had living in Alaska. I didn't carry any Nymphs or dry flies. Buggers, Egg Sucking Leaches and eggs are about all I used for trout. Even for Grayling I used a weighted woolly worm and streamers. I tried dry flies on Grayling but never caught the size I did with subsurface. My favorite big Grayling fly was a Burlap Streamer.
