When you say “a tobacco similar to Capstan,” I’m not sure whether you’re looking for similarities in form (flake), flavor (a medium-strength blend), or constituent leaf (all-Virginia). But here are some thoughts if you’re looking for a Virginia flake:
If you can find it, Peterson’s Flake is quite good, though it will be a lighter flake—in every sense of the word—than Capstan Blue. But it’s still very good and well worth checking out. (What I mean is that it’s not so light as to be flavorless.)
If you have access to Samuel Gawith, their Full Virginia Flake is my #1 VA flake. (The Capstan would be a close second.)
I’m not too familiar with C&D’s output (I haven’t enjoyed many of their blends), but I don’t believe they produce a Virginia flake. However, if you have access to C&D, perhaps you can also get GLPease. And while I don’t believe Pease produces an unflavored Virginia flake, he does make an all-Virginia blend, Union Square, which you might enjoy. His Embarcadero is also quite good; although it’s a VA/oriental, the orientals are barely there.
But now I’m probably far afield from what you were originally looking for…
