I've been considering adding an Epic GPX to my stable of boats. I'm attracted by its 31 pound weight and reputation for sprightly performance. I would like to expand the versatility of the GPX by learning to use a bent shaft single blade as well as the usual double, almost as if it were a pack canoe. This would make good sense in narrow streams and twisty salt marshes and just to make the overall paddling experience more interesting. I suppose that I might need to add some seat padding to raise the level of the seat a bit for efficiency but I think the GPX should be stable enough to allow this. I would like to hear from those with experience with this sort of thing.
