Don't think your harder cheap baits are going to outlast a z man... As much as I dislike their stuff, they are durable and have good action.The softness is a double edged sword. The Berkley jigging ones are pretty soft also. When I am after panfish with the smaller size, I sometimes switch to some cheap harder ones (I have one of the every color blister packs) or swimming ones when the bite is really hot because they last longer.
Now that there gets my head spinning!My favorite was Mr Wiffle that is no longer available. I have used a hole punch in the tails of other curl tails to make something similar.
