My obsession was using the OEM #10 wire from the roof to the basement.
x2.
Buy MC4 cable, cut it in half, plug and play. No roof junction box. I have yet to see a plastic box that will stand to all year round heat and UV where I am - and they all look ugly :)

The OP has 3, 24 volt, 230 watt panels in series, going to a Outback 60 charge controller. He is contemplating adding another panel or two.
The question is how would you wire it or rewire it and why.
Now I recall that old thread. Should've probably bought TS MPPT 60.
The question is - again - what he is going to wire, "another panel" or "two". And, - what panel(s). There can't be a definitive answer without a defined input. A debate can be. Series, parallel, series-parallel, mismatched or not, thinner/thicker cable, J-box, here we go again, round 4.
How about you answer the question twice. Once for one added panel and once for 2 added panels. And before you ask, the added panel(s) will be identical to the panels already in place. Should be simple enough.
