If 17" is your minimum radius, virtually ANY N scale equipment will look good running on it! You left Unitrack off your list of factions of N scale track warriors! Maybe it's just me, but if just the entries and exits on curves can be held to longer radii (i.e. sectional track 'easements'), the trains run and look better, without consuming the space of a similar overall minimum radius. I wish the modular standards would incorporate this.
