to begin, i have a few sections of 16" tiles as well
i must say the red/white striping does add to the scale look in a very good way.
here are some comparison pictures i took tonight.
here is a 24" realtracks tile over a mini-96 rcp track. the size is actually very close.
here is a 16" tile over a 24" tile over a 3 tile wide rcp mini-96 track
here is a tile finish comparison with the 24" tile and rough side rcp tile
here are 4 mini-z's on a 24" tile. it's very scale width but too tight for several mini-z's to race competitively unless you have some tight lines.
as you can see here, the dnano fits more than comfortably on the 24" tile. i think you could easily race a couple of dnano's on this.
