I know a few of you guys here use the Nimbus to do dancing on the clouds. As I'm talking with more prospects, I'm seeing a lot of reaction when I talk about Dancing on the Clouds and sparkler fountains. Depending on how much money I have left after bathrooms and HVAC, I'm thinking about investing. Regarding the Nimbus, what's the big difference between the Jr. and Sr. (???) versions. I know the big one needs a 30-amp circuit for the dual elements (not a problem) but how do they compare for runtime and output? Here's my dance floor (below). Would appreciate any advice or thoughts in regards.
