This has always been a debatable point amongst Nixie tube users and basically it boils down to personal preference. In saying this coarse grid Nixie tubes are far more easily read at a distance compared to the fine grid versions which are better at closer distances.
A lot depends on the format of the grids used, tubes such as the XN-11, GNP-7A have a very good grid format whereas the IN-14 is a poor example. One of the best grids is the horizontal grid which gives the best clarity in viewing and the ZM1232 is a good example of this.
But in the end, beauty is in the eye of the beholder.
Scott, that is a nice tube. I have never seen / used tubes like that, though would love to.
I have thin grid IN-14 tubes, and I have made IN-14 clocks, I really like the thin grid tubes better... but.. robust grids like IN-14 have a quality all their own. Makes them look stronger some how - more Russian I think.
Did the levitating clock ship yet? I soo wanted one last year.
