Yes, it will go much lighter... and far better upwind. After doing a 8.5km upwinder pretty quick I learned that. I do tricks and Jumps with it too now.
First time I tried it in Italy when Armin switch with me out o the water. I wondered what he was on to go upwind so well...
There are "very" special things about it. More than a Raceboard for Sure!
I'm working on all the riding details of the Flyrace, to pass onto customers... to make them more successful and faster - more fun to Ride! How to use and set up the fin....
One fun addictive board in many ways!

Even with a Smaller kite...
Flysurfer or Inflatable!
