Just a couple of thoughts to muddy the water.
I find that poppers that sit a little tail down work better. This helps them pop or chug more easily as you retrieve them, since the cupped face is constantly trying to face up.
You can achieve this by drilling you tail hook hole over sized, and adding lead there. If you're using a through wire, you'll probably have to experiment with a sacrificial wire, one that you don't mind cutting off and throwing away, to be able to adjust the weight. With screw eyes, just hang enough weight on the tail hook to get the lure to hang down a bit, and then put that weight into the over sized hole. You'll have to re drill for the screw eye, and use one that's long enough to get into the wood again.
You can try to add the weight by drilling the lure body next to the screw eye instead, but most poppers are so tapered toward the rear that there's not a lot of room in the wood to drill.
If you're using a through wire, you can leave the tail section long enough to wrap lead wire, from a fly tying shop, onto the shaft before the hook attachment eye.
You'll probably wind up making a few before you get one that works the way you want it to.
So don't invest the time in a great paint job and topcoat until you've tested the lures and got one that works.
Been there, done that.
