I own a 2011 Epic GPX (37 lbs.). I find the boat to be nicely made, reasonably stable, and quite fast; it's also a really nice looking boat. However, I agree with a previous comment that the GPX does have tracking issues. Maybe this is not a problem to some? Those who paddle on rivers might appreciate the boat's nimbleness and easy turning. On lakes, though, it's annoying that the boat goes into an immediate turn whenever you stop paddling. A skeg option on the GPX would have been nice (I plan to add an aftermarket one). One other thing - I'm also not a fan of the GPX seat. The back band is not adequate support, in my opinion, and I've also had problems with chipping away of the black plastic finish of the seat bottom.
I bought this canoe for a specific purpose - to paddle around local lakes and do water clarity testing for the Minnesota Pollution Control Agency. I like the boat a lot - it's stable, it tracks well and moves along nicely, and despite its size, it feels roomy (especially when compared to similar size kayaks) . . . and did I say that it's extremely light? Fit and finish are also good, but I would change a couple of things about the boat. The seat, while getting high marks for simplicity and elegance, is not very comfortable - the wood slats need a pad of some kind. Also, the foot rest/bar slips a little while paddling when you put pressure on it over time - adjustable kayak style foot pegs would have been better.
