Here is a study that mentions a critical aspect of the issue of canard flight.
High angle of attack allows for very fast roll rates in general. A wing
designed for high angle of attack becomes a superior wing in general.

Where does it say that? What was the max roll rate of the Wright Flyer? AJ-37
Viggen? A-4E Skyhawk? F-5E Tiger?



SNIP a ton:
The two fastest 'rollers' Iknow of are the F104 Starfighter and the
F5 series.
The 104 clocks out at about 420 degrees per second - note the Flight
Manual limitation is 360 degrees of roll - if below 1/2 G, 180
degrees. This is to stay out of inertial coupling, which is a really
good idea..
The F5 series is credited with 450 degrees per second. I have never
flown a T38 or an F5. so can't speak to that.
However, I have done maximum rate rolls in a 104A. This requires the
pilot to grab the canopy rail with his free hand to brace himself
against the lateral acceleration. Otherwise he will be slammed
sideways in the seat and inadvertently take out some aileron.
Additionally, if he desires to roll out at any given bank angle he has
to start recovery with about 45 degrees to go. The 'book' says 90, but
that's for non-acrobatic/ACM-current pilots.
It is difficult to see the value of higher rates of roll; it's hard
enough at 420 degrees per second to monitor what's going on outside
the airplane. But that rate of onset/recovery sure does make for
snappy pointed (hesitation) rolls and counters scissors by dissimilar
aircraf very nicely.
Hmm. something new - an anti-bot countermeasure!
