I think I'm ready to get off the GTD train. It's still a (mostly) good system, but I seem to run into interference issues every now and then (today for example) and that's just too much. I'd like to have a rock-solid performer that has both lav and single headset (very thin line, single ear) that will plug into the bodypack. I'm looking at the Sennheiser XSW2-ME2 as a possibility. What would you recommend?
