My first Royalex canoe and I have been wanting one for a while. I would probably have rated the canoe a 4 due to some tracking issues I have had with it on larger rivers etc. but when it comes to all around effectiveness and comfort this is by far the best canoe I have paddled. I would say it is best suited for smaller rivers or if you are on open water keep up your speed to keep her straight. I have had it loaded with my Wife and two children and it seemed to handle the load very well. I never really noticed it being any more "tippy" than other canoes either as in some of the reviews I have read. I like the capability of it being a trip canoe with family and gear and also working vey well as a fast solo boat. Also being very light and easy to portage and load on your own. Very pleased with canoe.
I will say that it's a great handling canoe, easily turned, not great for straight line tracking... but the biggest problem I had was the stability. It seemed to have little initial stability, even when loaded, and I had a hard time enjoying the ride, even solo. Secondary stability, on the other hand, was great, and you could lean it to the gunwales without too much fear. I could never get past the tippy-ness of it, and moved on to a Spirit II.
