Prefixes FTW-FTZ and FFA-FFZ are now listed as 2018 Wilkins/Poloz under the Polymer "Vertical" Series. Any suggestions for a better name for this series are welcome.
Thanks for doing that and also removing the two incorrect FTW and FTZ entries. It looks like the BOC has not yet come up with the official name for the new series. "Vertical" series sounds just fine for the time being.
