Wave maker suggestions and opinions

Hi all looking to go away from my 2 power heads opposite end of tank to something bigger and better at moving water. This is for 6 ft long tank 16" wide and 24" deep. I still have dead spots now that's why looking to change i was looking at the orbit 4 and placing on one end

I do 2 gyres on both sides, one horizontal and the other vertical, random flows.
