I vote for orange (mat and somehow fluo) I play golf and use mat orange balls. When the sun comes down I can still see clearly the ball (next to the flag of course...).

I had the 7 mostly foe foiling from 15-17kts Used it a few times in small waves and it was great. I now use Boxers for foiling and light wind wave sailing, they work great but not in the upper windrange (not "rock solid" like 3-struts kites) One (and no) strut kites are fur sure grunty, you can ride...

I use One strut kite (Boxer) for foiling but it happens to be very good in the waves (not overpowered tho)
They have a very good low end.

Ketos has different wave wings:
- wave span 500 - surface 570
- wave xl span 575- surface 790
- 1200 span 660, surface 1200
The smaller the faster. I guess 30knots with the wave and 25knots with the wave xl
All compatible with the different masts and the same fuselage.
best with XS stab
