As a side note about resonance, a tip I picked up here a couple of years ago is, when you don't need max power, plug up one of the outlets on each side. This lowers resonance ALOT! I tried, based what I'd read here, racketballs and they worked really well. Once I saw that they worked, I wrapped them in electrical tape since they were blue (to minimize the color and keep it from being too obvious what I was doing)
Good luck!
