It's not about open vs closed - it's about how undersized the valve ports are and how tight the bends are. No point in making a big open loop if you then make the air perform a sharp 180 on exit back to the main tube. Particularly when the design it's supposed to be superior to had that aspect better worked out decades ago already.

The playing difference between a good 70s/80s 88H on the valve and a good Gen 2 88H on the valve is noticeable, whether the Gen 2 is "open" or "closed" wrap. The playing difference on the valve between a good open Gen 2 88H and a good closed Gen 88H is pretty minimal. The main difference is the opened-up valve design that came in with Gen 2.

And as I said earlier many orchestra pits do not have room for the longer tubing behind the player...the wall gets in the way!

I have a great blowing Bach 50B (Bb/F) for sale. Early 80s vintage. It's very open on the valve and superb pedal register. It's well used so a bit scruffy, but has good slide and extra tuning slide for E (pull to Eb). Looking for £800. Chrs

50B is a single plug Bass, a bit too big to be used as a tenor at .562!
