The Progressive B definitely had some more clarity and definition over the Pressurewound B (for a couple of reasons). The Pressurewound B is still really nice, but like that set in general, it's more mellow and a bit darker sounding.
Out of the two, I still prefer the Progressive B. May look into stringing up my six with a Prog B and then Pressurewound E-C and see/hear how that works.
I've got a 34 inch scale 5 string coming in. I want to put something a bit darker than rounds but not as dark as flats. I usually like a tapered string but I wanna give these a go as I really dig the PW's.
I have thought about combining the Progressive B with other sets as well. The Progressive B is amazing.
