Cheers for the explanation. Turns out I got it wrong, both ST are the same in the 56 size, but a difference of 1 degree in HT which I guess accounts for the shorter reach, slightly offset by a longer wheelbase.
Basically there's too many factors at play for me to fully analyse what the difference would be, but the answer is probably fuck all.
Exactly, probably fuck all. Some people can be sensitive to the smallest change in bike fit/geometry; usually though, it'll feel well different to start with but you'll get used to it in no time.
