My Paselas are 27 x 1 1.4" & measure 32mm width with digital calipers. Yes, I'd love wider ones too without having to go the "cross" knobby versions. I tried some 700c wheels on my mixte (which sports it's original 27" wheels), and I thought the 700c wheels looked "insignificant" compared to the 27". I know there's not much of a difference in size, but the overall gestalt on the bike was not aesthetically pleasing. You will have more tire choices, however, if you go 700c.
