Hi, I don't know if this is a good place to ask and if someone already asked similar thing, but i need a bit help.

I have a small problem understanding how and what balancer should i build when i try to harvest big ores like this:

(idk how to add image other way).

Should i firstly somehow merge those 14 lanes into more saturated lanes and then use 7 to 4 balancer (i only want 4 belts) or should i build straight 14 to 4 balancer? I would really appriciate a little help with that. I'm not new to the factorio, but some things still aren't clear for me. I hope my english is enough to understand. Ty

So the super compact layout is a bit annoying to balance since half of the belt has half the mining drill count.
Without lane balancing it doesn't really matter if you do a 14-to-7-to-4 or 14-to-4. at the output one side of the belts will have 3.15x usage and the other 4.0x (because oversaturated from 6.29x), so a max throughput of 3,575x. Half belt short for full 4 belts. You'd need a 14-to-7 balancer to have the most throughput out of this patch. (this is when not considering future mining prod research)
I myself would just use the Compact layout since it doesn't usually cause this miner count difference so it's easier to balance.
