Interesting post - I should adapt your level of persistence!
Regarding the "no leg drive" - I fall into that practice if I am in conditions too scary
but otherwise use legs alot now. If you have gotten to the point you can paddle in those choppy conditions, why not add leg drive to your stroke? It might help your rotation..
As to "shorten your paddle" - that is a very good point, and one I wish I knew the answer to. How short is long enough or how long is too short?
Duh....is there a way to know (besides not being able to reach the water) when you have the paddle too short? Does it have anything to do with how much you have to lean/reach to bury it when you plant the blade?
Thanks for your post - I will now try harder!!
