Hi and welcome to the board from Alberta, Canada.

You've mentioned a couple of cigars I like a lot:

RyJ Churchill
Oliva Series V
Bolivar Royal Corona

I'm a little surprised about the Oliva's. I thought it was real hard to get other brands (aside from Cuban's I mean) in the UK. If you can find them, anything by Padron is good (at least, I think so) and if you like creamy and can find a Rocky Patel Vintage 1990 you might enjoy that.
