That is what I will do (right now they just go on and off). I also think most people are doing that. I have heard the east to west mentioned, but I have not heard of anyone actually implementing it. In terms of real life IMHO the four to eight feet of ocean we are simulating will not see different level of sunrise or sunset. Also as mentioned I don't know of any controller that handle more than 4 channels, doesn't mean there are not any.
