The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
I've been rigging my rods the night before (or morning of) a trip with a fly already on the tippet, then just 'break' the rod down in halves and slide the whole thing into the case. get to the river, pull both halves out and assemble the rod, pull the tippet then leader out through the tip-top until line itself is free and begin casting.
