All of my Taylors (including the Baby and the GS-Mini) sport PBs nowadays - except the NS32ce. They just seem to round off the tone of each and every one. I've tried many many different kinds of strings and always come back.
I was really anxious to try out the "Reds" - I figured if PBs sound better than 80/20, then the Reds should be even better since they have even more copper in their alloy. Unfortunately, my first pack of Reds had a couple of defective stings and they sounded awful. They quickly sent me a new pack but I have not yet had a chance to try them out - the Elixirs last too long...
