generally the larger the format tile the wider the notch and the more deviations in the floor the deeper the notch.
You are aiming to end up with complete coverage of the tile back when the mortar notches collapse.
The 20w x 10d trowel will be perfect whether round or square, but if you want just one trowel for general use wall and floor then a 10x10 should be fine for those tiles, make sure you back butter the tiles too to minimise voids.
Watch out for bowed tiles too, whilst theres not really anything you can do about it, it might affect your laying pattern, for example if laying brick pattern you might get some lippage where the centre of one tile meets the adjoining end joint on the previous course.. On the subject of lippage for large format tiles consider using lash spacers or similar.

is the bow along the length or across the width and how much is it. lay a level across the back and measure.
If the bow is uniform and across the tile it shouldn't cause too much problem but if it is along the length then brick pattern would mean that where the ends of the tiles join that would be the lowest point, but on the next course the highest point at the mid point of the tile would line up with that.If lined up rank and file style then all of the bows would match and although there would be a very slight ripple along the floor the edges would all match.
best bet is to lay some out on a perfectly flat surface and see.

Thanks, will lay a few rows out in morning see how it looks, the bow looks to be in length direction, slightly textured tiles not smooth porcelain.
Although i'd prefer brick pattern, laying long way pointing away from you as walking in room would fit nicer, less cuts though.
Another point, do you run the trowel in the longest direction? so beads run longest length or do you lay tiles with longest length at 90 degrees to the trowel direction?

As a rule we go by this when selling, something we got sent a good few years ago.
Planometric Tolerences
With the increasing popularity of large format wall and floor tile we wish to remind you that the tolerances allow for a 0.5% warpage in tile planarity. therefore the european norms allow on a 60x60 tile 3.5mm tolerance between the centre of the tile and its corners.
This causes no problem whatsoever when the tiles are fixed in the normal draughtboard pattern, however, it can create problems if the tile is fixed brick bond or half bond particularly in the case of rectified tiles when the joint width is reduced to 1.5mm. It is advisable in this instance to ask your client to check for acceptability BEFORE fixing or alternatively to consider bonding 1/3 - 2/3 which will have the effect of halving discrepancies in planarity.
