while a good string set (any average set) is generally homogeneous with maybe a few exceptions, the "good" B string is strongly affected by the "freshness" of the B string, by the "rightness" of the B string (its build/tension/diameter/set-up is it any good on this bass?), by the overall quality of the bass self and its overall proper set-up. Do not forget a good amplification.
Always in general, for the low B it is really difficult to express an opinion, an objective one, after a simple three minutes road test. 35" basses start with an implied "stiffness" advantage vs. 34", but there are tons of good sounding B 34" basses around; just check yourself on any occasion you'll may have: you will be amazed.
I don't think that "freshness" has much to do with the quality of a B string.
I also think that opinion is never objective and voicing an opinion is what I did in my previous post.
To me a 36" bass just sounds bigger and therefore better( no ,it's not imagination
The comparison between an upright piano and a larger Grand piano is the best way I can describe what it is i am talking about
That is not to say that I dislike short scale basses.
I like them, but for other things.
