HI just installed 600 square feet 4" wide white oak 3/4 select and better. There is little over wood floor is mostly flat. I realize no floors are the same but any general feedback on how long it might take using the rental orbital versus the ez sand drum (home depot rentals)? If it's 5 hours extra I would rather use the orbital to be on the safe side. If it's 2 days I would go with the drum.
