Thanks for the input guys. I actually ended up picking #3, after comparing it with tons of exemplars I am very confident in it.
I agree dj, it's weird how he can go from #1 and #2 with major signs of speed, to #3 being slow with big "stops" (like the "a" you are talking about). I've seen a lot of examples where it looks like that though, even the black JSA one to the right of the graphic I made has the same first "A".
When you look at that comparison closer, you can even pick up on traits of where his strokes are "bolder" on certain parts of certain letters from pen pressure. You can see this across multiple examples (circled in red). Also formation of certain letters, such as the "l" in "Hal", is identical (circled in green), and the "n" (circled in blue). Definitely same hand IMO.
