Depends on if you have relatively long legs or a relatively long torso. Relatively long legs - go with the smaller size to get the shorter top tube. Relatively long torso - go with the larger size to get the longer top tube. Normal leg/torso length relationship, back to the tossup - larger frame for higher bars, smaller frame for lower bars or lighter weight.
