Grade all the slate first. That is, go through all the boxes and put them all into 4 piles, thick to thin. Start with the thickest. You can then start off with a 8mm trowel, then to a 100mm trowel as the slate gets thinner. That way, you can save on the addy. The floor has to be dead flat for this method.
If the mid-to thin slate does go under the height of the thicker tiles with the 10mm trowel, I back=butter with a 6mm to make up the difference.
Good luck. PS, seal twice, once after grouting. Continue to change your water when removing the grout.
