Hi
I rode the first Spitfire for a long time, about 3 years ago, liked it a lot, and very lively, so fun in waves.
But too small by the standards in wing size we have had over the last many years now.
Last year I rode the XLW for some time, with a 108 cm pocket board.
It had the perfect size for waves and fun, in terms of wing area/lift.
The reason I did not continue, was it was slower turning than my wavefoils with small stabs.
So for fast waveriding and turns/yaw, not as good IMO (if it is "big" canard specific, but I think it is).
And this should be the very reason (for me) to go canard
So the rearfoot bias was overshadowed by this lower agility, for me.
