Progressive Press and you're not even looking at reloading 1,000 rounds a week? WOW, I do more than that in 2 evenings with 2 single stage presses side by side.
I only shoot maybe 200 rounds a week, and I load on a progressive. Time is a premium for me. I like to spend a few hours and load enough to last a long time.
Some people have more time on their hands, and some people have less.
Do you work those 2 single stages simultaneously? With both hands?
