Lately, 965. I rotate through tins and finish them off before opening another, keeping around three open at a time. One of those will be my "go to," always a straightforward english. Westminster, Ashton Consumate Gentleman, 965 and even Nightcap and SOTE Flake have all filled this role. Currently, I'm close to finishing off the 965 I emptied into my pouch and have a tin of Nightcap waiting.
So really, whatever English I have that I know, like and have open.
