Obviously: being a fictional universe there aren't really hard and fast rules for these... personally: always preferred the idea that the class development patches were triangular while the individual ship ones were round but that's just me.
Hopefully you like it Lig; sort of pulled the Romulan Republic logo there out of my arse given well: the inspiration for this one being the Normandy (a co-developed ship), and needed something to make that third look less empty... but it did also fit given the shape that came out once I'd done the silhouette.
Also damn you Lig: your sketch wasn't symetrical! *OCD twitch*
