Yup. Dublin is a very solid English blend and all that, easily equal to a handful of quality English/Balkan blends, as aldecaker sez.
1865 is more so, with more Latakia and other quality ingredients. I have them both open, side-by-side, nose-to-nose, and 1865 is a darker (special 150th Pete) blend. Both are fine additions to your smokey rotation.
