Always love seeing you post pics of the Alpina, it is such a pretty, classically built and configured bicycle. As to tubs, personally I use glue, out of habit since 1979. The modern tape is much easier to use, and cleaner to boot.
I thought about switching to clinchers on the two C&V bikes I have, but after getting feedback here I kept them on, and I'm glad that I did.
