UV Gray, Tube Fly
Gray minnows are common in lakes with a gray rock or gravel bottom. The UV flash mimics a number of baitfish.
Additional Info
Tube Flies are not just a stand alone lure. I think of them as a part of a flexible system. You can “Stack” two or more flies to increase the length or to create a two-toned fly (chartreuse + orange + fire tiger). You can change the hook from the #2 Octopus style to a treble, tandem singles, larger or smaller. The hook can be moved farther to the rear of the fly by placing beads between the hook and the tube. One customer stacked 4 white tube flies with a #1/0 treble to imitate a mountain whitefish and landed a 20#+ mackinaw at Flaming Gorge, Utah. The best value is the 10 Tube Fly Selection, where you have a number of flies to work with.
These flies can be rigged and trolled in a number of ways. These flies can be fished “naked”, just the fly and manipulated with your rod. The Jay Fair method and ripping are a couple of ways to fish just a fly on a sinking line. Dodgers are another popular way to animate the flies. Dodgers limit the speed range for trolling without rolling the fly. The Wiggle Fin Action Disc #1 is an excellent way to animate the fly at any depth. With the #1 disc on the nose of the fly the materials will be lifted out by the turbulence produced by the disc. At 4 to 12 inches above the fly, the fly will have a narrower profile and a tighter vibration/wiggle. A Wiggle Fin Action Disc #2 makes the fly jump back and forth similar to a dodger. Some anglers have tied in swivels with a bead or the Slide Lock Bead to hold the disc up the line. A video with underwater shots of many of my flies rigged can be seen here: Fly Rigging Video.
Due to increasing inflation costs I have been struggling not to raise my fly prices. To maintain my fly prices, I will no longer be sending an Action Disc with each Arctic Fox Trolling Fly.
