My SWAG (scientific wild a** guess) is there are going to be enough diversions in the tank that excessive flow won't be a problem.
My 36 bow has a big piece of driftwood with Anubias all over it that stops a lot of water flow in the bottom third of the tank. Additionally, my rainbows and other fish seem to really like the flow in the upper reaches of the tank.
Edit to add-
I plan on positioning as follows-
Spraybar on the left side of the tank, water blowing from left to right, some surface agitation.
1 Koralia Nano powerhead pushing water from the top back left corner of the tank to the top front right corner of the tank, angled up, providing more surface agitation agitation and promoting a flow loop that helps push detritus to the filter intake
1 Koralia Nano powerhead purshing water from the back left corner of the tank to the bottom right corner of the tank, helping prevent dead spots along the backside of the aquarium- an area riddled with dead spots
The newer powerheads are great, as they're far less concentrated that the older models. Plus, they're small enough that they aren't nearly as distracting. Finally, in my tank at least, the flow is still pretty gentle.
