I agree with you mostly. But for the sake of argument and in bitog fashion, define "too thick at starting".
My only point here is that pressure and flow are nearly instant no matter what oil you use as long as it's acceptable in the climate it's used in. No reason to go thicker at startup when thinner ones are available but I don't necessarily agree with giving up HTHS for thinner startup vis in an engine that never sees freezing temps in the winter and is constantly operated in 100F weather in the summer.
I would not run a straight 50 unless it was something like Redline straight 50 which is more than likely a 15-50.
