Who would know this could be so hard? I test rode the P2C in a 56 and a 58. Is it possible for one to feel a tad too small and the other a wee bit too long?

I'm leaning towards the 58. Does anyone know what the minimum suggested stem length is on that bike? I forgot to check the length on the one I rode today, but I'm guessing stock would be 100 or 110? In anycase, I need to ride it again and do some adjusting. I'm thinking my hip angle is too open right now. FWIW, I'm 6'1. Any other 6'1 riders out there and what size P2C are you riding?
