Since the Noe is one of the classic bags I feel that it is one that I have to think about getting eventually. Is it a comfortable bag to carry or is it a classic that looks good displayed on the shelf only? Do you use it a lot or do you use your Speedy more? I already have my mono Speedy 35 and would not want to buy the mono Noe if it is not a bag that will see the light of day. Also, is the petit more comfortable than the full size Noe? TIA
