A wide-open draw is often provided on high-end (expensive) artisan pipes, so you might get used to it and like it. I haven't tried it, but I believe the 6mm adaptor available from SP and other retailers might restrict the draw slightly, if you decide you want that. Like other members on this thread, I have refitted several of my cobs with Forever stems, and have bought several of the special edition MM cobs with acrylic stems that are a little more expensive (about $28 right now) but don't need to have the soft plastic stems replaced. Over the years, I've come to regard MM cobs as permanent pipes. Since I have a large rotation of briars, cobs, and other pipes, they don't wear out.
