I am 5'1 and just recently bought a 15in 7.2 FX. At first I worried it was too big but I wanted to save a few hundred bucks rather than get the 13in 7.3 FX at a different store. Fortunately, as I have been riding, I noticed that once I get off and going, I sort of "settle in" and the reach feels fine. But yes, you are very luckily the store is so patient. Good luck :-)
