+/- 80 gallon cube tank - powerhead question

[reef tank 2.0]

When I had my 135g (6ft) set up, I started with a number of Hydor 1500 power heads. I really disliked the look of those powerheads, so I decided to try Gyres. I swapped out all the Hydors for (2) Maxspect Gyres (200 series), One at each end. Those were awesome. I was so please with the result / performance. I don't recall ever having issues with them, except for the controller. But that Maxspect replaced that free of charge and that was the last issue I ever had.

Now, that that tank is no more, and I am starting this 80 gallon cube, I'm thinking of doing the same. Obviously the size and quantity may differ, but I'd like to try the Gyres again. Biggest issue to think about is how powerful will they be and how much water will they send up and over the glass of the aquarium, onto the floor. The orientation I am considering is vertically on the back glass, one on each side of the overflow, maybe 1/3 - 1/2 the way down.
(I still have my original ones, but I think they may be too large. I also noticed they have been discontinued. )

For those of you that have a cube roughly the same size as mine, have you used Gyres? have you also used regular powerheads in the same tank to see which works better?
Care to share your experiences between the two?

maxspect gyres are still awesome. I use this one in the 50 gal frag tank, and that's all the flow I need other than the return.

using only one gives you enough flow for corals? no dead spots?

yes, but my tank is shallow. In your situation, maybe get 2x 2k versions instead with one on each side, as you suggested.
