Those recordings really sound good. It's hard to record in a church-often you pick up too much room noise-people breathing, squeaking seats, etc.
Didn't know a Jecklin was any benefit with cards, but it seems to work.
I think the C-2's are underrated, especially for the money. Nothing but rave reviews on the net except for here on taperssection. Musicians seem to love them. I got a pair because they were so cheap (under $60 with a stereo bar & clips) so small and many positive reviews. Used them once so far and the recording came out quite well.
