I have 740 and 810 BCS, 930 HPS, 899 and 1099 ARTs and have used all windwing. I bought the 740 for kite foiling however it's fantastic for windwing as well, the 810 for light wind kite foiling and turbulent messy water but a good around wing.
Love all my wings.
However, if I was only to have one combination it would be the 930 HPS with 350p stab.
Having said that currently the 899 ART is my favourite from 11,12 kn wind upwards.
The 1099 is excellent light wind and fantastic however, I need to commit more for jybing and frequency fail but getting there.
My next acquisition will be an Advanced fuselage and expect it will work well with the 1099.
While I continue to incrementally make progress turning 76 next month is my excuse for my skills.
