I've narrowed my search for a reversible easy-fold down to the Baby Jogger Versa but am struggling to decide which version. I like country walks so am tempted by the GT wheels but from what I've read they don't claim to be all terrain so I'm wondering exactly how much the different wheels improve the performance over rougher ground. Does anyone know?! I've fallen a bit in love with a red one but only the standard version comes in other colours - the GT is black only. I'm prepared to give up my red dream if the GT is much better performance-wise.
