Yep, the C is your friend.  

I also find that an inwater return makes for a nice easy correction.  Instructors I've spoken with often talk about having your paddle in the water.  The paddle's no good if it's not in the water.  You're much more stable this way.

Practice with the bent is key.  I have no problem with a J using my Grey Owl bent.  

Short strokes are more efficient & powerful.  Reach, stab the water, stacked hands, torso rotation, recover/correct as bottom hand passes the knee.
