We have switched over to cast iron also, tired of replacing teflon pans every 5 - 7 years.
While the newer, pebbled lodge works ok from the factory, I smoothed mine out with an angle grinder and flap disks. It takes about 15 - 20 minutes per pan, and use a respirator!!! My snot hasn't been that black since baling hay as a kid. I try to get it as smooth as possible, but there always will be some grind marks and depressions - but that's a good thing. The seasoning grips better to a surface that isn't super polished. After all that, check out "The Culinary Fanatic" on youtube, Jeffrey Rogers. He has the best seasoning routine, IMO, and really knows his cast iron. He's a guru.
After searing steaks, baking cornbread, etc., cast iron is king in our house. Nothing else comes close to the quality of cooking that cast iron provides, IMO. The big thing that I've learned is to always preheat the cast iron first. I seldom have problems with sticking.
You can also try carbon steel pans. Mine don't retain heat quite as well as cast iron, but they are much lighter and have long handles that can usually be held without oven mitts or towels. My favorite brand so far is AUS Ion, from Australia. They offer both a glass smooth finish, and a very slightly pebbled finish, and they both work wonderful. They are pricey and worth every penny, and come with a multi - century warranty. Handling, washing, and season for carbon steel is identical to cast iron. 90% of the time, it's wiping it out with a paper towel when finished and you're done. No need to wash, heating it up on the stove the next time will kill any and all bacteria.
All of you reading this are in an elite club - you actually know the difference between carbon steel and cast iron, lol!
