Great airplane. I've had mine for about 5 years now and it is always a pleasure to fly. I have a Saito FA82 in mine and it is more than enough power. I fly with 60 size GP floats and it has plenty of power off the water as well.

The 120 will be heavy and too much power IMHO. The real moth flies slow and graceful and the FA82 does just that. I fly around on bout 1/3 throttle and rarely go full power.
