I am getting new rubber on the Zeph today, and have the option of Metzeler ME33/55 or Bridgestone BT45 (and whatever the corresponding front is). I've read all the reviews that I can find, and the argument seems to be about 50/50. Many reviews are also (unfortunately) written from a european standpoint, where they have colder weather and different road surfaces. Does anyone here have any meaningful comments about either model? At this stage, I'm leaning towards the Metzeler, only because I like the look of the tread pattern.
