Not a thing wrong with tying jigs, even for someone who enjoys fly fishing more than with other tackle or not at all with other tackle! 
I tie more jigs now too than I do flies. Several of my customers are tournament anglers, walleye & bass, and they don't use fly gear, so I provide what they want. It's a bit funny to me, I like tying hair jigs for bass, and bucktail jigs for Stripers, but some of those guys just want big marabou jigs. Nothing fancy, just big & with a "better" quality hook. Most off the shelf marabou jigs are small & cheap. These guys believe they have an edge over their competition. I mold all the jigs that I use, various styles. Each has it's uses.
Denduke, I really like what you're doing! They all look great!
Some of those trout would end up on my dinner plate too! It's been a long time since I've caught any of them however. 
Capt Mike, you've posted some of your jigs before, and I've always liked seeing them! I've copied them somewhat & some of your flies a few times, when I wanted to tie & fish something different than what I usually tied! Gotta go with what works! I'm real fond of that Sparkie style head too for inshore fishing. 
Mike Chell, yep, I agree with you! Even if cast with fly gear, they're still jigs. Although, I've tied "flies" on small jig heads, they were of a size that was easily cast with even 4 or 6 wt fly gear. No heavier than some tied with beads. Start getting up to & over 1/8 oz, and not something I would even want to use with my fly gear, even the 10 wt. That's why they make sinking lines, so no need to have the fly weighted that much or use a jig head. That's why they make other tackle too! They both, flies & jigs, catch plenty of fish when used in the right time & place that's for sure!
