@daizee, can you expand on that?
I went through a long period of coveting the newer, sexier cast iron. To an extent, i still do. There is no doubt; they have more precise and refined manufacturing.
In Australia there isn't as a huge vintage market. Similarly, boutique cast iron does not have much of a presence either... and the shipping would be astronomical! I was excited when Lodge released their Blacklock line - not necessarily because they were 'better' than any of the other new generation cast iron (they are 'worse'). I was excited because Lodge have a big enough distribution network that it was inevitable Blacklock would be sold in Australia... and it now is.
I eventually handled a Blacklock skillet in a store and was underwhelmed. It was a bit deflating! I know simply inspecting one is a far cry from cooking with it.... But the pan just felt insubstantial compared to the regular lodge offering. Certainly not what I have come to associate with cast iron - a thermal freight train. There is a strange irony there given that part of the attraction of the new generation pans is that they are lighter. But that felt 'wrong' in my hands. Perhaps that is just a case of misaligned expectations?
I have also done an about face on pan smoothness. I probably have a good claim to the (once) smoothest cast iron on KKF. Years ago I polished one of my cast iron skillets to a near mirror (just because I could). The smoother the better? Right? I got frustrated with how poorly the seasoning adhered to the surface. To resolve this, I roughed up the surface with low grit paper. Even then it took a
long time to accrue durable seasoning. It does seem like a textured surface helps the seasoning adhere! The best option might be a machined surface (so it is flat) followed by low grit sandblasting for texture.
I am on the edge of buy an Aus-Ion pan. I am semi-interested in a carbon steel pan but don't need one. Aus-Ion looks like a carbon / cast iron hybrid... somewhere in between with regards to thermal mass.
