Knowing the large number of threads on the subject of tires, I tried to focus my question on preferences between the BT57's or BT020's. Since no one even mentioned the 57's, I'll take that as a "no confidence" vote. I used to be a Metzeler person, and went through 2 sets of MEZ4's on my old VFR. In both cases, I got good mileage/handling, but the front tires wore on the sides into a triangular profile, and started feeling pretty non-linear once worn. I then tried 020's for a season on the VFR and was pretty happy. Price is better too. Guess I'll try a set on the Bird.
