We are looking to do some kayaking on the Futa and other rivers in the Futa area in Feb or March of 09. Looking for a good company to go with. We've been talking with Expediciones Chile and have looked at RXRivers.com and Bio Bio Expediciones also. Does anyone have any first hand experience with any of these (or other) companies? One of us is a solid class IV boater (comfortable on some class V) and one of us is only a solid class III boater (has done some easier class IV). Any feedback/suggestions? Any thoughts on who might have the best selection of boats? Would Feb or March be better? Any info would be super helpful. Thanks.
