To answer the question someone asked in your blog about how the B-Lines compare to Hetre's or Pari-Motos:
B-Lines are a decent "every day use" tire, much like the Panaracer Pasela. On a "quality per dollar" basis I say they are just as good as the Hetres, but that is because they are a fair amount cheaper (just like Paselas). But they are nothing like as plush as the Hetre's. Once you've ridden on Hetre's, it's easy to rationalize that "this ride is more special and deserves the Hetre's" and leave the B-Lines on your other bike. And for events where speed is of the essence, like a 600km brevet, the Pari-Motos just can't be beat. They are nearly as plush feeling as the Hetre's, but noticeably lighter and faster rolling. But you give up some life expectancy, so you really only want them on your bike for the serious events.
