I've been running the FlashFlo for 2 years now. It preceded the Palos and was intended for hiking. It's not as voluminous as the current crop but I made one modification to the hose routing I recommend for anyone considering going fanny style:
I too was concerned with catching the hose on the seat and not being able to sip easily from a waist mounted hose. Instead I cut a small hole in the top center of the pack and route the hose up the center of my back and over my shoulder (ala backpack style). The Flash Flo came with a small hose clip you open/pinch to whatever shirt/jersey you're wearing. The hose was just long enough to do this. I can sip as easily and regularly as with backpack/hydration and the hose never gets hung up.
