I've tested multiple times, for accuracy, and I would have to say that I'm a 9, 4/6 times, with the other 2 being 5's. I personally don't feel like I fit 5 as well as I do 9, but neither the 1 or 8 wing types fit as well as 4 does. I've read that the wing type for a 9 can't be a 4, but it is a 5 wing type. Could I just be Mistyping myself more often than not? 5 doesn't sound like it isn't me, 9 just seems more like me to myself.
