Reading about Touring, Looking for info on trailers,

I'm reading The Essential Touring Cyclist by Richard A Lovett.

He describes touring and the special needs of a bicycle tourist. He has a pretty good overview of things so far though there are some things I wish he'd covered in more detail. I'm only about half way through the book so maybe he'll answer things in more detail later.

Things I'm interested in finding more about are.... trailers. BOB vs Burley. Why would one be better than the other? The prices are close. Most of the trailers I see in pictures on touring reports seem to be BOB trailers. The recumbent store I've been too carries Burley but can order BOB's. They didn't give me any really good reason why one is better than another and are happy to order BOB's if you like. Burley says they will carry more weight (100 lbs vs 70 lbs) but I'm not too sure I want to carry a lot more weight! The guy at the store said he has a BOB but it's not stable if you put more than 40 lbs in it. Another site I saw said 50 lbs was the magic number for stability at his height ans weight. I haven't seen any reports on the Burley. Does it matter if you use a recumbent trike? More stable closer to the ground? Less? And what about a tandem does the combined weight of the tandem and riders make it more or less stable? Lots to figure out. I guess not a big deal as I have lots of time.

Weigh-in tomorrow. I'm hoping for good news.
