Hi, sorry, I keep putting the wrong the questions in the place! So please excuse me while I still learn the ropes of TPF. Anyway, I would appreciate comments from tpf'ers who have the small classic flap and those who have the medium/large flap. I notice there is only a small difference in the dimensions of the bag but I would like to know if there is a big difference in functionality? And am I right that there are only 3 sizes for the classic flap - the small, medium/large and jumbo size? Please do let me know what you think! Thanks!
