Totally non-canon, save for the V-8 (BOP). The V-9 is a good up-grade from that; increaced power and a second plasma torp.
My opinions now, the V-27 and the V-30 are good new tech ships to counter the Connie refits, and the K'T'Inga classes. Also the FASA's Romulan answer to the Excelcior class of the Z-1 Nova class starts to take on the TNG look of ship building.
There are a few other designs in the FASA SRM that might also be apropreate with out really tweeking the known canon information.
Here's a link that has some schematics of the FASA ships http://www.shipschematics.net/startrek/romulan.html
The V and Z numbers are used in the list so just look for them by that.
