The window trim we are planning to paint is on the 3rd and 4th floors

Your job, your brush. But I think it's odd that someone
concerned about today's latex paints not being good enough thinks
using a cheap throwaway brush for window trim is a good idea.

I don't see this. I am looking for the paint that will last the longest.
The longer I can go between paintings the more money I save. The point of
disposable brushes -- for oil-based only -- is also to save money. I pay
for my painter's time. It takes time to clean oil-based paint out of a
brush. That time would cost me more than a $1.73 brush.
