as mentioned already. In WW single blading, emphasis is on pulling the canoe with the blade. Tom Foster has some DVD's out, and I remember him marking the canoe, if looking from the side bow to the right, with tape at about 4 o'clock and 5:50, which is approx. where your paddle shaft is when the blade enters and exits the water in ww paddling. Just bombing down the river can be different, but this is good advice for eddying, rock avoidance, and boat control in the frothy stuff.
FWIW, I use AB Edge paddles in Carbon and Fiberglass reinforcements. Prefer the softer glass in shallow rock strewn stuff, and the carbon for bigger moves.
