I reassure you, stroke survivor, I've just bought a zen. (it was a joke, I hate begging here as elsewhere!)
Seems you better had bought a full vented for the windconditions we have last days in Belgium. At least, here in Antwerp its strong winds. Over 20 mph (5 Bf) whit windblast to 40 mph (7Bf). So no flying for me whit my standard.
