Solo Tripper

I've been learning about canoes from all of you on this forum for the last few weeks - thank you! In the market for a solo canoe to either sit or kneel and paddle single blade. The Swift Keewaydin 15 and Colden Wildfire top my list currently. I can't figure out the rocker deal and how that effects the boat. Keewaydin 15 has a bow rocker of 2" and a stern rocker of 1". The Colden has 2.5" on both ends. How does this effect my tracking and maneuverability between the two? Any recommendations on these choices from your experience? Thank you. Jim.
