I think she felt too upright on the Trek because the head tube was 15.5 cm (compared to 14 on the Diva) AND the stem on the Trek had a significant rise. You're right about a smaller top tube giving a more upright ride, but 5mm shorter won't make much difference, although the shorter head tube and no or negative rise stem will make a big difference, so I think I'll be ok.
