Honestly the only thing I get a little sticking with in my CI stuff is cod fish. I make a cod picata and no matter what I do, how much or what type of oil cod sticks. Floured, unfloured doesn't matter. The only thing I have not tried is making it with butter and never will because the smell of cooking butter makes me nauseous. I see on TV all these chefs and what not singing praises of "brown butter" just point me where to puke. I have nothing against butter BTW. I cook with it but I cannot get it hot i.e. to saute or fry something in. I will fix my scrambled eggs in it. and they don't stick i my CI pans though for convenience sake I tend to simply use my All Clad non stick stuff. Easy to work with, easy to clean, non toxic (no PTFE) and rugged as all get out. I can even use metal spatulas in them with no problem.
I like a good assortment of pans. I have everything from full tri ply stainless (both from All Clad and Tramontina), heavy anodized aluminum commercial (actually made in USA), my All Clad non stick collection and of course my cast iron stuff including dutch ovens both raw CI and porcelain LeCruset and of course my bare carbon steel wok
