Making a UL spybait

UL Spybait Challenge

I got an email from a buddy who asked if I could make a UL version of a spinbait for trout fishing in the mountain streams of North Carolina. It seems that Duo Realis discontinued the spinbait 60 and now only makes an 80 and 90mm version. I couldn't even find a 60 but I remembered that I had one. I am a jig and spinnerbait guy, I've never made a hard bodied bait before. I took on the challenge because I felt if I was successful, I'd have a hell of a bluegill/bass bait for my own pond on my property in NC and the rivers I fish here in Florida.

How I went about it: I'm not ashamed to admit I made a 1pc mold of the 60 and cut it down to the length I wanted and sanded it to the necessary profile I was looking for. I made both a 1 5/8" and a 2" body.

But with that came the issue of properly weighting it so that it would fall flat horizontally with that sexy little shimmy. I needed to add weight to a solid body, not a bait I could assemble from two halves with spots for the weights molded in place.

I molded about a dozen bodies and then had to experiment with weighting the baits. I needed the bait to do two things........swim straight without wobble and fall perfectly horizontal with that sexy shimy like a Senko. I drilled a series of small holes ahead of and behind the belly hook and filled them with tungsten powder. I got really lucky and pretty much nailed it with the first two baits I made. Next I mocked up a bait with the screws and hardware I would use to complete the bait to test it.

I swam some of the baits in the pool and found that they blew out and rolled if fished too fast. I simply bent the paddles of the lead prop the opposite of the tail prop and this was instantly corrected. The bait fell exactly as I wanted it to and it swam great. I would decide to use Decoy single hook's on the 1 5/8" bait and Gammy trebles on the 2".

At about the time I was knee deep in the project, I read on Tackle Tour that Duo made the Tetra Works mini prop which is a ul version of the Spinbait. Despite the bait being rather difficult to acquire, I managed to get one and here is a comparison photo with the 1 5/8" bait I made.

Here a few smaller ones @ 1/8oz ready for clear coat. I used my copic air brush to paint them.

2" baits are about 3/16oz. I was going for small in the sense of length and profile. A slightly heavier bait in moving water or deeper water like the quarry pits I fish could be a good thing.

These are essentially the finished baits in both 2" and 1 5/8".

A couple were also specifically made for deep water.

Here is a family tree of the 90mm, 80mm, 60mm and 48mm baits from Duo and a couple of mine.
