I'm 5'1, 30 inch inseam or whatever. My legs are definitely not long & my torso is not short... I've found what works for me best is a 73 degree seattube angle & 165 mm cranks, top tube about 540 mm. A 73.5-74 seat tube angle ends up with me riding the bike with my bum hanging off the back of the seat in an effort to get comfortable with the location of my knees, even with a setback on the seatpost.

My carbon frame,I pretty much bought because it had a 73 degree seat angle, and it's the most comfortable of my bikes.

The litespeed currently has 170 mm cranks on it, and I've been trying to ride them to see how it works... I can manage, I definitely get more knee fatigue, and that's why I'm eying new cranks for that bike.
