Soldering of the pins

I have to solder the pins on Portenta Breakout and I'm undecided whether to solder them downwards to insert an underlying motherboard that has terminal blocks or upwards and use flat cables. :thinking:

I don't really like Dupont cables.

How did you do it?

Wire wrap headers have long pins. Sockets on top, pins below.
