My Arundel (only use one for now although I have a second) on the other hand... four years now and not a single ejected bottle. And I descend a lot of roads like Tunitas Crk, Bolinas-Fairfax, Alpine, Alba Rd, and other SF Bay Area goat trails where the pavement frequently resembles cattle crossings. Can't remember what the Arundels cost, but it only hurt once. (Unlike looking for my water bottle in a roadside ditch, which hurts every time.)
