Default Sloshing: Turbulent/Laminar/Inviscid?!?!

I'm searching for opinions on the best way to model sloshing in a rectangular domain with air/water. The sloshing motion is pure sway motion: A * sin (omega * t). I have all the required UDF's, etc... I was just curious about the proper viscosity model. It seems that you can get away with inviscid flow for small amplitude waves. However, once you get near the natural period of the fluid you can get resonant conditions. Higher amplitudes lead to breaking waves and fluid hitting the tank top. I've tested all three viscosity models but what really dominates the flow?!
