Just bought a 5.5m Armstrong wing. says 8psi maximum. What do I pump it up to? 7 psi ?

Some expert riders play around with the pump psi, especially for wings with dual inflation, but I think it's best for most of us to just follow what the manufacturers are recommending. I've owned the V2 wings from 2.5-5.5 and have pumped to 8psi UNLESS I was dealing with conditions wherein the variance between sustained wind speed and wind gust was more than 10kts (with many holes throughout). Only then would I pump the LE and strut to 7psi to make it easier to manage the gusts.

Thanks
8 is great
