Hmmm as overheads. Dunno. They have such a sweet sound, why waste it on the drummer.

Actually with the 61's excellent rejection I almost tried it last week for a live show on a kit...But then it's such a sweet mic and I didn't want my drummer clobbering it and having to kill him and then spend all that time searching for his replacement!
I haven't used LD's as overheads, but I'm sure if any mic can, the 61 can make cymbals sound smooth if that's what you're after.
As compared to other toob mics...I can't stand the solidtube. Solid doo-doo to me. Harsh and unnatural. But that's just me, a delicate artiste.

I had a brief encounter with an NTK and they are very different mics. The NTK has more hype in the bass and top end than the 61 which can make the NTK a better choice with certain sources. And there is just something magical in the midrange on the 61...it just sounds 'right' in a very musical way. At least on string instruments. To me. But I don't get out much.
I've had not heard the TB1 yet. I already have a C1 (doesn't everyone?) and it has its uses as a 'pop' vocal mic and can sound pretty nice on the Oud or guitar, but compared to the 61 it's one-dimensional and hyped.
Before I rant on and on, can't you beg/borrow/rent a pair of 61's to try for yourself? Only you know what you like. Or must you buy sound unheard?
I'll stop waxing on about the 61 and let you go and listen to it and report back. Ok?
