So good to hear "love" stories like this
Indeed, I have it the same way - if marginal winds I use a really big and high AR wing, just like your XLP wing just even bigger.
When light winds and small kite, I might use a high AR medium sized fast wing.
But in ALL other conditions, I prefer the wave wings, both big and small ones, lower AR, fast turning, and amazing fun
Good to hear you have found your "call" (for now).
Dont worry about other foils - the Alpine foil seems like an awesome well designed and well built foil
(only thing I dont like is the sharp nose, but it can be sanded round)
