I've never heard anything but good comments about Brebbia's, and mine is one of my favorite pipes, so I'm sure you're will smoke well.
I've always been interested in trying a meerschaum lined briar, but not interested enough to actually buy one. There was a vendor a couple years ago selling NOS meer lined Grabows for reasonable price, but it's wasn't one of the popular vendors, and I forgot what website it was, when I found the site a couple months later they were sold out.
I will be interested to hear about how you're smokes. In theory putting meerschaum inside a briar seams like the answer to the question that no one ever asked. It's almost 99% guaranteed that it's a pressed meer bowl, which everyone poo poos about how they are don't absorb moisture like a block meer. Inside a briar, which is used to make pipes used because it's fire retardant, and absorbs moisture, but maybe I'm missing something.
In my world, everyone's a pony and they all eat rainbows and poop butterflies!
