Thank you for the kind words.
I usually use one of my large Makita 7" or 9" angle grinders outfitted with 7" flap disc from Heleta (use the 7" because I haven't found a 9" one). The bigger grinders are a lot heavier, but it doesn't take as much force or time to take the material off, so your arms don't really get tired quicker. And then I switch out to a complete 4.5" set up for the rest of the rough sanding. Then use one or more different styles of DA sanders for the finish work.
Here is a look at the difference between the more common 4.5" flap disc and the larger 7":
And one showing the difference between a 4.5" Makita vs a 7" one:
