here's my 27" frame with 700Cx23's: http://www.cs.pdx.edu/~marius/pics/fix2/3.jpg
Shrimpx,
That is far from fugly. Nice ride. I ride a 700c in the rear and a 27" up front (to solve the brake reach problem). No problems at all. Running 700c puts your pedals closer to the ground, but I've not noticed it.
Happy riding.
