Howard, my brother flys his Kadet Senior on a pair of my 34" floats and a friend flys his Senior on a pair of my 42" floats. Both setups work fine. Actually the 34" floats look too small, but the plane is so light it doesn't need the floatation provided by the larger floats. What seems to work well is to have the float step near the CG of the plane and have a couple inches of float ahead of the prop. I saw a Cub, that had the floats set back too far, go over on it's nose as it taxied away from the beach. I think it was a good thing it happened there and not while he was landing. I too think a set of 33"-36" floats would work well for you.....Seaplane
