I've not felt the B strings to be that much different to anything else that has a good B already, Lakland, GB, Sadowsky, Alleva Coppolo, Roscoe etc etc and only a touch better than my Musicman Classic5 which is only 34", that said I do like them and I'd happily buy one if I liked the sound of it. The Tribute you have is already a good bass as are most once you get out of the very budget stuff, the difference between a £159 and £459 bass is much larger than those between £459 and £1459 imo and ime.
