Tunze Nano Wavebox or VorTech MP20?

[Slick Fork]

While I was switching tanks, I briefly tried the nanowavebox out on a 33gallon, It was a fairly quick wave but a pretty cool effect nonetheless. Now I have it on my 4x2 foot and I get about a 1.5-2" wave and you couldn't talk me into giving the nano wavebox up if you tried.

My understanding of the physics of the thing is that the wave is created by displacement of the water and so you wouldn't get the same kind of effect as you would with a vortech or series of streams.
