Well, I've got a pretty complex (some might say convoluted) personal canon system. There's stuff I classify as 100% canon, and then there's stuff that's near-canon and semi-canon; near-canon material is material I consider mostly canon, except for a number of small details, while semi-canon material is material that is the complete reverse of near-canon - material I consider non-canon except for a number of small details.
So, if you want me to go by what I consider 100% canon, here's my "personal canon".

(I'd just like to note that when I canonize comics, I don't take the art into account, just the written prose and dialogue; so I don't take drawn hairstyles, clothes, lightsaber colours, etc. into account during canonization).
