Hey guys, the GF and I are taking a trip to Moab over Memorial Day weekend. We're only going to have two days to ride, so we were thinking of doing Porcupine Ridge and Slickrock. Since niether one of us has been there before, I'm not sure which bike to bring, the Foes Fly (42lbs) or the Trek Liquid 25 (32lbs) . She'll be riding a Juliana superlight, so she'll be fine with that. What do you guys think I should bring?
