Comparisons: Shires 1.5L: BA MV42: BA Bach 42 Open

[Bonemaster]

Good morning,

Looking for some feedback as to the differences between these pipes.
I have been playing the Shires (it is the Shires that works best for me). I have the BA MV42 in seamed nickel but not much playing time. Have not tried the BA Bach 42 Open.
Sure would appreciate some 'based on my experience' comparisons of the Shires to either or both of the others, as well as between the BA MV42 and the BA Bach 42 Open.

Thanks!

Bob
