The Flex Fleye is an awesomely simple fly designed by New Jersey’s own Bob Popovic. The fly utilizes UV Flex which gives the fly incredibly realistic movement that predatory fish find hard to resist. You can tie this up in various colors to match the baitfish in your area, but we’re tying a mackerel imitation in anticipation of striper season here in Maine.

Material List

Step One

Start the pattern by establishing a thread base from below the hook's eye to the bend.

Step Two

For the underbody, tie the Flat Diamond Braid below the eye, then cover the material with thread. Be sure to leave the rear material exposed.

Step Three

Next, wrap the Flat Diamond Braid material up the shank with tight, overlapping turns, then tie it below the eye.

Step Four

Secure a small clump of ram’s wool on top of the shank with the material extending past the hook’s curve, then clip the forward-facing material.

Step Five

We are now working with SF Blend for the Flex Fleye’s body. Secure a section of the white-colored material above the ram’s wool with fibers extending past both sides of the hook. Pull the forward-facing material rearward, then make several supporting wraps in front of the fibers.

Step Six

Moving onto the UV Mackeral SF Blend, secure a smaller piece on top of the white SF Blend, fold the outward-facing material back and make additional wraps for security.

Step Seven

The Flex Fleye’s tying portion is finished after securing two whip finishes in front of SF Blend material.

Step Eight

Flex Resin is crucial for giving the Flex Fleye its movement and enhances the fly’s durability. Apply the Flex Resin to the head, then gently work it rearward with the bottle’s tip, creating an even resin layer.

Step Nine

Now that the first coating is complete, hit the fly with UV light to cure the resin.

Step Ten

Immediately after curing the resin, apply the adhesive eyes on both sides of the shank.

Step Eleven

The Flex Fleye is nearly finished, but we need to apply one more coating of Flex Resin over the eyes.

Step Twelve

Run the UV light over the eyes, and the Flex Fleye is ready to hit the surf!
