I wouldn't give up on the gibbs completely. Maybe buy one and see how it works out. Don't just go on what you heard. I bought a few gibbs dannies this winter and they swim fine.
I would definitely get some tattoo 2 oz. darters too.
Darters don't "swim". They're supposed to have an erratic action, more of a sweep than a swim, if you can picture that.
Gibbs darters still catch. I carry Gibbs, Superstrike and Tattoo darters. There are times when the fish will show a decided preference for the Gibbs. I accept the fact that they can split and crack. I still have to have them in my bag.
