I am a huge fan of Brigham pipes, with (as of now) seventeen examples of their work currently in my rotation. The maple filter system is, in my opinion, far superior to any other filter system for the simple reason that you can still pass a pipe-cleaner through them (Savinelli's balsa come a distant second for me).
That said, there is one major drawback you need to be aware of with Brigham pipes. Although the company is Canadian, and the original designs are Canadian, it is not cost efficient to manufacture their pipes here any longer; and as such have turned to an Italian factory (the same factory that makes Capri and Lorenzetti). These pipes are easily identified by their delrin tenons (Canadian made feature an aluminum tenon), and although they are well made, they feature a sodium-silicate (waterglass) bowl-lining, which isn't so cool (it doesn't allow for moisture to absorb into the briar). This can be removed, but it is a serious pain in the behind. Coincidentally, neither the Capri nor Lorenzetti lines seem to feature the solid pink bowl-liner.
Huh - thats a 2 dot in my avatar, neat.
