I'll want to see how well the dials can be swapped, first, but if they work well, I would probably go in for two sets per faction, right off.
I like how sturdy they seem and they appear to eliminate the problems that will eventually occur with worn dials.
An unnecessary luxury item, for sure, but I'm playing the long game here and would like to be able to play the game for years to come without worrying over-much about the cardboard componants.
For casual games, these look like they would make it crazy easy to make up a custom dial for special occasions, as well.
