I think I am.

It is my profound wish that you delay meeting him as long as possible.

The closest canard type to yours is the Cozy Mk 4 - the same planform
and airfoils, the same engine, the same number of seats at the same
fuselage stations. Performance-wise, the only big airframe difference
is the retractable main gear (and the horrible back end of the SQ's
cowl.)

Generally speaking, a Mk 4 will touch down at about 75 mph - 100
downwind, 90 base, 80-85 on short final. Significant forward CG (in
the 98" range) heavy gross weigh or cross winds might add 5 mph or so.

Those are about the same numbers most people use for a Long EZ with a
big engines. Berkut with a 540 is a bit faster, it will touch down
closer to 80. A light, small engine EZ will touch down a bit slower,
in the 65-70 mph range.

The difference between a 75 mph touchdown and a 90+ mph touchdown is
significant. It's a 44% + increase in your momentum. I know the
Matco W50L's are good, but do you want to get rid of that much of the
margin?

Low speed handling is significantly improved by trailing edge fences,
you may want to look into them.
