I remember my instructor telling me the difference between paddles and how I will want a paddle that is large and twists up the way and not down so as to pull the multi finsih up and not drive down and the smaller the paddle the more mixing the more air through the finish the faster its going to go off .
my 1st paddle was frome screw fix cost me 45 quid was haif the size it should of been and twisted the wrong way , the finish goes of on the board or at least 10 mins sooner than it should on the board, havent had that problem in a while....
