Fit is such a personal thing. Some will feel better on a small bike, and others will opt for the larger, depending on their anatomical factors and their riding habits.
I've also noted that there is a great deal of variance in bikes themselves: Sometimes a small bike will feel larger, whereas a larger one will feel too small.

The best advice I can offer is to take no one's advice at all. Try it for yourself and decide, and if you get lucky, Harry, your Int'l may feel like a tolerably good ride. Best of luck!
