If you've got long legs then 180mm might be the way to go, but I'm really not sure what constitutes 'long' - I'd guess you're pretty borderline.

Worth remembering you lose 5mm of ground clearance, probably nothing but if you're already close it might be.

I bet you couldn't tell the difference...

well if 175mm never gave you any probs why risk it by getting longer ones?
