The measure of a good swimbait is how much the tail hangs to the side when you’re holding onto it by the nose. To more it hangs over, the better the action. Unfortunately, those baits are rather stiff thus the lack of action(I have a few packages of those baits). They might serve well for a more aggressive speed, but I haven’t had much time to play with them myself so I can’t honestly say for sure.
Good luck fishing with them. I hope you find a niche for them this season. If I find one, I’ll be sure to pass it along.
