Hauntedmyst - your pipe looks very similar to a few of my 50's Heibe sandblasted Goldpoint briars. Don't suppose yours is also a Heibe?
I've got a few Dublins. One of my favourite blends is MacBarens Plumcake, except for one thing, it bites.
That was until I tried Plumcake in a meerschaum lined 50's Heibe Goldpoint Dublin. No bite at all.
I've a few larger meerschaum lined pipes that do not fix the bite issue.
The Dublin is not a big bowl which helps & I'm sure that the meerschaum lining goes a long way quelling the bite from Plumcake but I do wonder whether the Dublin shape has something to do with helping to ameliorate the bite issue.
Recently I bought a bent Road Town [Chinese] Dublin Sitter. Once I sanded off the disgusting carbon lining, it's become a rather good smoker.
