I would suggest getting a handle on the cause & remedy of the floor
sloping.....this sort of thing usually points to foundation issues.
Active or dormant? recent / ongoing / old?
This need to be done before you worry about R&R of the subfloor.
btw what's your joist spacing? previous subfloor sizing?
What's wrong with the subfloor that you're thinking about replacing
it?
cheers
