Vauen is probably my favorite brand of Briar pipes.
I was initially attracted because every pipe they make is a Filter pipe (and have a wide variety of Churchwardens, a combination that's pretty much impossible to find anywhere else [I should also mention Big Ben]), but they're also technically excellent and I keep coming back to them for their designs (which vary from purely outlandish to very practical and affordable).
The only thing to be aware of with Vauen is that they drill their draft holes on the narrow side (around 2.5mm if I remember correctly), it's not horrible, plenty of factory pipes are about the same, but if you're accustomed to something like Castello then Vauen is probably the polar opposite in its draw.
