hey ponobill sounds like you have a outrigger canoe background , the reason i say this is when you j stroke in a canoe usually the steerer or seat 1 do this .
in a canoe when u j stroke that rather than u pull the blade towards you from the front you place the blade to your side (about 90 deg) and pull sideways to drag the ass end of the canoe around .great for stuffing up your back muscles because you lean out of the canoe so much to do it and ur right that type of j stroke would unbalance u quick ,
IMO( and i could be wrong big time) i believe it is a sort of j stroke almost a cheat j stoke for SUP ....seems like a small stoke with a flick to it ,done by twisting your wrist at the end of the stroke before you pull out the blade???
I'm not really sure this could be a total miscommunication
thanks for the kind words 62mac i am stoked i love sup I'm alive again!
check this guy i'm sure most of u have seen it already..
