I have seven of the French-made Comoy's pipes, purchased over the past couple of years. I'm drawn to their shapes and the honey oak stain of the Tradition series. Six of my pipes are from their Tradition series, including a 337 Prince. The other is Comoy's 2016 pipe of the year, a slightly bent pot.
Comoy's pipes have attractive grain for their price, and their stems fit especially well. All but one are drilled dead on. The other is very slightly to one side, but still on the bottom of the bowl. That's the prince, actually.
Comoy's has one consistent quality control problem: the beveling on the chamber edge. Six of the pipes have a beveled chamber, and four of them are noticeably irregular--five if I'm being picky. Some portion of the rim is beveled properly, then it fades, with the remainder being hardly beveled or not at all. Probably some machine is out of alignment, but I like to imagine that Pierre the Beveling Bastard, besotted with wine and un-fireable under French labor laws, is the source of the problem. It's a better story.
FWIW, I figure the beveling flaws will become even less noticeable with regular smoking, and the pipes are very attractive overall. Also, the two pipes with the best beveling are my most recent purchases. Maybe Comoy's is getting better about it. Maybe I got lucky.
I own no Savinelli Roma or Onda pipes. One of my Savinelli's has slightly irregular beveling. It would fall into the "being picky" category.
