These are all Yoyos I’ve seen and thought about. But the one thing that all of these do not have is a Fingerspin cup. I have all the Yoyos I need, and each of them has a trait that I love in a yo-yo, but none has them all. The main thing that these Yoyos lack is a good grind finish or no Fingerspin cup. Yes, you can Fingerspin on anything, but I particularly like Fingerspin cups.
I personally like the feel of finger spinning on a flat cup yoyo more than a centering one. Also, many of the fingerspin style yoyos don’t catch all the time and sometimes just spin on the outer rim if you don’t land close enough to the center. This is an issue you don’t have with flat cup yoyos so your margin for error is actually higher with flat cup yoyo than the VAST majority of yoyos actually designed for fingerspins
