Thank You very much for answers.I read every one of them,i wont lie i'm a little biased towards smaller 52 frame.
My current bike have around 54-54.5cm top tube and 9 cm seat to handlebar drop and i find it very comfortable.
I prefer smaller bikes so i think 56 is out of question.
So its between 52 and 54 frame.
Thanks again,will try to get on both of them or something similiar today.
