PRO-tagonist tip: Bora V2 PSI
The Bora wing should be inflated between 6 and 7 PSI. At first I didn't think at all about the difference in PSI. Since the introduction of new materials such as aluula and hookipa in the world of wingfoil, everyone talks about how amazing stiff wings are. Consequently, I pumped up the wing to 7 PSI all the time.
As I have written before, the Bora V2 is a very very rigid wing. It's almost like a cambered windsurf sail. The power, speed and continuous acceleration is unmatched.
However, this also means that the wing can be physically demanding when you're fully powered in the upper wind range of the wing. Luckily, as it turns out, there's a very simple solution in those conditions: deflate the wing to 6.5 or 6 PSI. The difference is massive. You keep the performance by gaining comfort and control!
Now I inflate the wing to 7 (or 6.5) PSI at the beginning of the sessions, go for a few runs and then decide if I want to deflate by 0.5 PSI. If necessary, I go to a quite spot and unscrew the valve a bit so a small amount of air gets out. After about a minute, I screw the valve tight again an get back to flying.
To give you an example with the 5.0: below an average wind of 17 knots the wing is at 7 PSI, above 17 knots it is at 6 PSI and around 17 knots it is at about 6.5 PSI.
