I hope this helps!
If you look at the datasheet for the black jaguar, it says 1e6 transitions per second. If you consider that there are 4 transitions used for quadrature encoding you get 250,000 lines per second. With a 100 click per rev encoder you'd get 2500 revs per second. That's 150,000 RPMs. The Jags should handle anything you can throw at them.
