Tiles are 250 x 750 - Trowel size!!!

Yes, quite significantly

Does back skimming really help adhesion of the tiles?? Wall or floor, only ever done this with travertine.

If the back of the tile has a deep profile, everytime....

perfect trowling technique: spread substrate with flat side of trowel then serrate, this compresses the adhesive and improves adhesion quite considerably rather than just applying with combed side of trowel ( its also cleaner Imo), then back skim tile. Now,... Assuming all that has taken you under 2 mins to do then you have the perfect adhesion when you twist tile in to place, only spread for 1 tile at a time with those! Tiles that size and above usually take me 10 minutes to set each tile so take your time. A rubber sucker will aid your leverage when moving tile in to its final position.
