I started experimenting with range and orbs, need advice !

First picture is my habitual way of running : min range, extra orbs going a bit over the black hole center, but most of my kills are done by the normal orbs right outside my range. And that's great to no get swarmed in late game and run tornaments.

But then I realized that I might loose a lot of coins because of that. And so I thought : if I increase my range, I can run the orbs right in the middle of black hole, and projectiles will allways push enemies backwards. This way, I'll only kill things attracted by the black hole, and so enemies that are in my coin multipliers (MVN). And when there will be protectors, they will survive the orbs, but with a second black holes proc a few minutes after I'll manage to kill everything, still in multipliers.

Is my logic correct that I should use the first option for tourneys and the second for farming ?

What could/should I change ?
