Default Rolling Problem

I have a H9 Cub on GP floats (60 size). The floats seam to be set up properly according the post from the Ontario Club and it lifts off the water nicely - but once in the air the plane has a strong tendancy to roll left. I have never set the plane up with landing gear so I don't know how it would respond on wheels therefore I'm not sure if one of the floats may be causing this. The stab looks perpendicular / parallel to the fin and main wing. The main wing has 2 deg positive to the floats.

To counter act the left roll I need to add 10 clicks of right aleron - this moves the trailing edge on the aleron one thickness (~1/8") up on right wing and down on left wing. This seems excessive and I was wondering if there is another way to fix the roll? The plance CG width wise is close to the middle (right side alittle heavy).

Can you use he elevator (since it is in two halves) to help compensate for the roll or would this create a bigger problem? If so, how?

Thanks for any help!
