Hello Roland, and welcome to WAGS!
Just a word of caution.... many folks have started using Flaxseed oil, and then get a few months down the road, and begin to experience some major problems with their beautiful seasoning flaking off, bit by bit, leaving nasty black particles in their food.
So for that reason, many of us do not use or recommend that particular oil. It's expensive, and does not appear to wear well. :)
