Why is it so hard to swallow the fact an aprox. 16-17m, mid aspect kite will not pull upwind a planing
as much as a 19m, higher aspect kite ?
As for a non-planing board like a SUP in ULW,
I have no doubt that the Infinity could outperform the 19 Core, since it's lighter and turns faster.
But I also call BS on the 2-4kt (aka 3kt at the kite) claim
Yes, there is a saying around here through many year what most of the people agreed on:
"THERE IS NO REPLACEMENT FOR DISPLACEMENT"
like a lower displacement engine won't give you the same torque or Pulling Power as the higher,
unless somehow you increase the RPM or like sine-ing the kite like crazy, which is not my style
I tried all the most advanced and lightest kites in history claiming light wind advantages, but so far
I couldn't find any kite brand which would honestly compete with the Pulling Power
of a higher aspect,
and larger size in light winds regarding my combined kiting & windsurfing experience only in light winds in 29 years.
Seems like so far when I've been testing some recent light wind Inflatable Kites and found,
they could be a compromise even with a higher speed, because the performance can be poor in the other following area:
High Bar Pressure in, mid & upper range
Disturbing flutter and vibration at bar in, mid & upper range
Less pulling power compared the same size
