I haven't done an A/B comparison but I think I can tell the difference between 73" and 74", sensitive soul that I am. I think perhaps because it's on the borderline between comfort and work.
I've got a 110 BCD crank so I can use one of those Sugino BMX chainrings which are about twenty quid on ebay. Not a huge expense. I can sell my existing one to recoup some of the cash. It's only had a few months use.
So really no difference between using big rings or small rings to get the same ratio?
