Those look really nice. Just a couple bits to consider. Keep in mind I know nothing “0” about Pool 4, but have been making my own jigs for years. From the photo it looks like you might want to shorten the tails to about 1.5 times the length of the hook or the amount of tail behind the hook should not exceed the gap of the hook. Longer tails usually create short strikes. You might also want to use a contrasting color for the eyes if your looking to trigger feeding strikes. For reaction strikes eye color is not so important. Not sure how craft fur moves in the water, but I mainly use natural hairs or marabou because of how it moves even when the jig is still. The movement alone can trigger feeding strikes. Again I’m no expert, but these have worked for me. Good luck.
