Pedal strikes are not really a big deal on my (standardly bb dropped, 170 mm cranked) road frame. SPDs rather than clips+straps helps a lot. You have to keep pedal strike on your mind in the corners but as long as you do youll be fine. I think it would only really become an issue in the most aggressive urban riding, e.g. crit style. I've only actually struck once and it was more of a gentle smooch.
