It seems that our canard gliders have a much smaller "sweet spot," and require a near-perfect launch angle and bank for a proper transition....Also, has anyone experienced significant launch differences based on different positions of the launch hook?
Canards are inherently longitudinally unstable. The Neutral point and the center of gravity are not the same as the "standard" configuration. So changes in the canard are far more sensitive then changes in a tail on the standard configuration. Thus, less forgiving.
That being said, moving the wing along the fuselage to bring the Neutral point closer to the center of gravity will reduce the instability but not eliminate it. However, a less forgiving launch and transition can be achieved.
