Though they are not cheap, Folstaffs are very well made and sturdy. Having done lots of winter fishing in heavy current, it's the only one I would trust that folds up. They are sturdy enough to really put some pressure on. Since the handle is cork, I leave it together and tether it out behind me from the upstream side. I've had mine for 15 years. I use wax on the ferrules to keep them from sticking.
The rod pointed downstream makes sense to me, as it orients you to be always moving perpindicular to the current- least resistance and steady pressure.
