Everyone compares their seatpost to Thomson, so why not just get a Thomson. If you like alloy, this is THE seatpost. I own two, one on my track bike and one on my mountain bike, and I would put one on my cross bike, but I don't ride it enough to justify the cost of a new seatpost.
I used to be a bike messenger and this was my everyday bag. If you like single strap messenger bags, this is a great one! It survived my abuse through the elements, and still looks almost new. Plenty big to hold anything you can think of and made in America. Beware people will try and push the seat belt button.
