Got a gig there next weekend - it's a church I record in regularly and thus have been allowed to permanently mount some flying stuff. I hope I'll be able to take more pictures of the ropes and their setup. It's just wire rope stuff from the German equivalent of Home Depot.
Thin and lightweight mic cables are important here. Klotz-AIS TwinPatch. 1 metre is EUR 15

. Great for Stereo and Straus packet stuff, since it's only one cable for both mics.
