Wise decision and you can't go wrong with their return policy. It comes down to personal preference and had I not been able to try Kestrels in both sizes before I bought the flex, there is no way I would have known for sure. People the same size prefer different saddle sizes.I'm just going to quit worrying about it until it arrives. There's too many reviews having both sizes that like that size. The part that I guess confuses me is why do all companies have a size change around 35"? Seems like one of the most common sizes out there. Why do clothing manufacturers switch to a 2" jump starting at size 34??
