The video doesn't show any problems. I would think that getting it on the finger is a trick that would be affected by low tactile sensitivity, but you do fine.
I am not sure how your problem will affect your tricks. Almost always you are looking at the top, so perhaps you can compensate, except obviously something like a catch with your hand behind your back.
For several regen tricks you need to let the string slip through the fingers of your non dominant hand in a controlled way. That may be a challenge, I don't know.
Anyway, I think skill toys are a way of challenging oneself in a fun way, not of competing against others (yeah, in spite of the contests I entered). And spintops will challenge anybody.
