Going from a AA to a A is only going to change your hole shot not change the dynamics of the boat. You can only go so slow impeller will not change that width, weight and hull degree will affect planning speed. to see what impeller you need find out what your motor top rpm is then run your boat wide open and see if you can get close to that I like to be about 2-300rpm below it. If you are over revving then go up in impeller size but if you aren't getting close to it then drop. Hope this helps.
