, but have you (or any) experience with 2.0/1.5/2.0 spokes? With classic usual DB, I never got problems (for decades).
Grab the time to wellcome the idea to push (gently) rims against wall/floor to relax spokes and (probably) unwind spokes winding. It sounds something better than nothing, a strip of dry marker can do check of.
Haven't tried spokes with 1.5 centers (and have no interest in it) but I built my last wheelset with 1.8/1.6/1.8 and it went really well. I think if windup ever were a problem for me, I'd rather do my side-loading
while adjusting the spokes so that I don't have to chase it later.
