The point you raised about user unsteadiness in strong winds was new to me but probably very valid.
Troubador had some very dirty weather up on Islay when testing the Harpia with its restricted exit pupil. No wonder he stayed off the Islay malts! .

PS:- I have been up to Meldorf three times in the last couple of years. The Speicherkoog is a paradise for wader watchers.
