Thanks, did you lift the floorboards and put them under? Wondering if I could use them above the floorboards and below the ply and save even more effort.
Spxtz-
yep, between the joists and the boards - but this was for downstairs where we left the boards as the finished floor.
don’t see why you couldn’t just use them between boards and ply, would recommend having them placed at the points you’re screwing the ply down as well (i.e. screw straight through them) as any ‚voids’.

used a lot of these for getting floorboards (relatively) level:

more work - but could take up the boards and then use 18mm (maybe 25mm even) marine ply atop the joists.
