Just like to jump in here and say the I agree with the time issue, BBS, but would also add in weather as a factor. Sometimes it's just too damn cold to be outside for 2 hours lol. Usually I go for just about anything from the Nub line, AF chateau fuente, AF short story or SLR series G rothschilde.
There are others that I have tried and truly enjoyed but I don't recall all the names. I actually got a package once of a bunch of short petites, the really small ring gauge ones, cc I think, and I enjoyed the heck out of them until they were gone.
