Without going off topic too much... I'd like to add what an excellent and friendly service I experienced on each occasion I've used Zurich for GA purposes this year. VFR circuits on 28 with an opportunity to mingle with the IFR flow on the other 2 rwys when permitting; Hearing the odd US accent almost as often as Swiss from the Tower and without the "only interested in the big-boys" mentality given just how busy ZH is.
Well done LSZH - a rare melting pot in my limited experience!

P.S. If you want to hear Zurich Radar at first hand...
www.navex.aero ...just use your volume balance control to select either of the available 2 channels.
