Obviously steel will be a lot easier to find in a variety of sizes. Bronze pieces are great but much more hit and miss. If you can find a good vintage Berg in good shape, that would be advice. You can find good new ones, but the consistency isn't there.
Thanks for your insight .. Tried a 130/0 at a friend's shop.. . also tried a vintage Vandoren Blue Jumbo T75 & fell in love . . so the question is over . . didn't like the feel of the Berg .
