Paul,
Sounds like you're waaaaaay fast in the pattern.  My Velocity is heavier 
than your plane, and for a long runway, I shoot for 80-90 kts off the 
180, 80 at the top of the glide slope, 75-80 over the fence depending on 
crosswind and 70-75 at the numbers depending on crosswind.  I use my 
belly board all the time for landing and carry about 1500 rpm, the 
theory (key word here) being that if I have a power failure, I can 
retract the belly board and continue the march.
Have you done any slow flight yet?  What is your canard stall speed?  
What kind of roll authority and pitch authority do you have at Vs + 5 
kts?  Vs + 10 kts?  I believe you'd be a LOT more comfortable around 
touching down where you want to (like on the numbers), stopping the 
airplane, etc. if you were slower in the groove.  Also, it's a lot 
easier to decelerate to touchdown speed over the numbers if you only 
have 5 kts or so to bleed off.
I try to minimize how much I have to decelerate in the pattern (past the 
180) ... Jim S.
