You have a very nice website, I couldn't find the Bari clip. I just got an older Keilwerth low Bb Bari this weekend myself. I just ordered a Metalite M9 mouthpiece because I need something right now to use. I've tried the V16 on a King Zephyr, a lot of people really like it because it captures the sound of a really good HR Berg Larsen mouthpiece. I'll be trying one again on the Keilwerth this weekend but I'm going to try some other pieces myself before I settle on something. I'll follow this thread with interest and share with you my findings.
