If you do a search on this site you'll find lots of discussions about carrying rods for backcountry canoeing.  Some folks like to use a 1 piece rod and keep it protected with golf club tubes and all manner of clever rigs that allow for good protection and maxiumum ease of access.  Some go with an ugly stick or the like and not worry too much about it since the investment is pretty minimal.  Myself, I prefer to use 2 piece rods which I can load up and have ready but at the same time stored in a rod case.  For spinning I pack a Shimano Compre 6'6" M F and like it just fine.
