fwiw, the primary advantages provided by Bev Seal Ultra 235 line are conveyed by its PET liner. This substantially cuts oxygen permeability, and perhaps more importantly eliminates the "plastic" flavor common to solid PVC lines to which some folks are particularly sensitive (a genetics thing).
It does have a broader bend radius than solid PVC (eg: the industry standard Bevlex 200), and what is sold as 3/16" ID line is actually 1/5" ID - so lengths are appreciably longer for the same dispensing configuration. And of course that liner conveys premium pricing as well, but on the up side the liner is much smoother than solid PVC and should clean up better and last longer...
Cheers!
