I also like the Sugino 26/36/46 crankset as mentioned which uses the traditional square taper BB. The only thing I might swap is the granny to a 24 which is the smallest the crankarm can handle. I run a 24 granny on my old LX crankset (which by the way looks almost identical to the Sugino) on my commuter/tourer.
Why square taper BB? Not for argument's sake; for my own education. TIA.
(I got an old Shimano square taper BB on my MTB. It's been barely used.)
