Yeah, I thought about the Brigstones BT020's. I see they are considerably cheaper than the other two that I have mentioned. I think they are also the stock tire for alot of bikes including the CBR1100XX. But my gut feeling, and I may be wrong, is that Michelin and Metzler put a bit more R & D into their tires. Besides the 100xx is a supposed improvement over an already proven tire; the 90xx. I've been a Metzler fan for years. They are of typical German mentality: methodical, detailed and comprehensive in their research, development and implementation of proven tire technologies. I've ridden in Germany for a few years... lived there. The roads are twisties in the back 40 and wide sweepers on the 'bahn. They know what people want in tires and they simply deliver. Michelin is very similar however, of the french persuasion for the most part. But, it's Europe. Not very many straight roads like you'll find in America, especially in out Western parts. I feel more comfortable with the Metzler or the Michelin tires. Maybe, I just understand a bit more about those companies more than the others.
