Which size tile spacer? - Tile Advice

[Totem]

I'm planning on installing coloured Bevel Metro tiles to kitchen splash back size 200/100 with a thickness of 7 mm.

The manufacturer recommends a minimum of 2 mm for grout line, I'm not a fan of large grout lines and am hoping to either use 1 mm or 1 1/2 mm spacers.
Has anybody had negative experiences or suggestions with tiles and small grout lines as in my project?

Definitely use 2mm spacers...

And 2 mm is not exactly a large grout line.

Nice colour choice of Grey grout on the gloss white tiles, is there a technique or special tool for applying grout between bevel tiles other than a flat grout float?

Funny you should ask that as our resident metro expert has just patented the design for such a tool
