Hi Thanks! it is very clear, no need for pic — I never thought that feathering the blades would make a difference, but I’ll try it (I have whitewater blades, by sheer coincidence, even if I am strictly a flatwater user). I might still get a 240 paddle even if feathering my 210 paddle improves it, on the assumption that greater length and feathering are better than either approach by itself.
