ok.. the clark kent bikes usually had high bottom brackets, and level top tubes... that might explain the shorter seat tube specification you mentioned, eh?...

your short legs with long torso might fit the bike very well... a bit longer steering stem, and a rearset seat post may be a good idea... the seat tube angles look to be close to, or the same as the head tube angles...

you might want to test ride a couple 58 and 60cm frames too... sadly, most larger frames lean toward long legs and short torsos, from what i've seen.. i always end up on a small-medium frame with a fairly long stem, and the seat slammed back.
