I have some large pipes that weigh over 2 ounces, and they aren't for clenching. Lighter pipes are easier
to use when you want or need to clench, and also a lighter briar tends to denote a briar that has been aged
longer and is therefore higher quality. I have a Britannia Dublin smooth 1/8 bent that, despite being
a lower middle grade in price, is delightfully light weight, and it is a full size Group 4. Smaller light weight
pipes are fine, but have their limitations. For most purposes, 1.5 to 1.7 is about right for a full size pipe.
Up to 2 is completely acceptable. After that, I want a lot of bowl to justify the weight, and it's not going to
be necessarily my go-to pipe. Some folks like only extra large pipes, and will accept the weight, and others
like only smaller pipes. What music to you dance to? (As the old saying goes.)
