Good lord.

> You MUST use flaxseed oil to season your pan.

Then

> You MUST NOT use flaxseed oil to season your pan.

Just season the fucking pan with some cooking oil and be done with it.

I swear, the internet has made some of the simplest things into this relentless pursuit of perfection.

flaxseed has an atrociously low smoke point (225 F). You really shouldn't be using it for cooking whatsoever, let alone seasoning cast iron.

In general I agree with your sentiment though. Find something that works for you and go with it.

I don't mean for my salty comment to justify a not-ideal method. But for this topic, the proper use of the pan will generate a good seasoning as it is used.
