I am collecting all the Jecht Spheres for Auron's Tornardo. I have found a list telling me where to find them. Problem is, I still haven't gotten the Tornado Overdrive and I can't remember which Jecht Sphere(s) I am missing. I am certain I can't be missing more than one or two.

From what I can see in my Items list, there is no way to see which JS's I've got as they aren't numbered or labelled in any way. Do I just have to go through all the places again to search out the ones I haven't got?
