travertine floor substrate

[atec]

hi all, got a floor to tile in travertine (filled). The substrate is wood (T&G). Some of the wood planks is very uneven, all seems to be secure but i will strengthen. The floor is also slanted. My question is i will be putting ply ontop but that wont sort the slant out, should i use self leveling compound or not, and if so on top of ply or T&G. Will the slc come through the travertine.

And no the leveller will not show through the travertine....

Ply the floor first and then level it.....then use an un-coupling membrane ..durabase ci is spot on for travertine floors on timber...
