Default Multiband HF Antenna Nipping | Bottom Up or Top Down?

I'm mulling the construction of a "nested HF squalos" antenna. At
least three bands, wires for 20, 15 and 10M in a coplanar arrangement
on four fiberglass spreaders. Basically a multiband cubical quad
driven element with a common feedpoint, single feedline and flopped
over into the horizontal position. After wading thru all the modeling
comes the real world. I'll cut the wires a bit longer than modeling
indicates and start manually tuning the thing to resonance by nipping
all the wires a bit at a time using the 259B, etc. Each nip will
affect the resonant points of all the wires due to the interactions
amongst the wires. The question: Which wire should I start tuning
first? I've seen posts which state that one should start nipping from
the lowest band to the highest band and I've seen recommendations to
start with the highest band and work down to the lowest band.

Which way is it??

Tnx, w3rv
