Privateer Ships from 30 and up

I was using my work hours to prepare a list of ships i would use yup till the 50s and i came up with this list, most are based on Armor and movability. Guns are secondary objective to me.

Level 30 "Cerberus" Heavy Frigate
Level 34 "Capricieux" Frigate
Level 37 "Myrmidon" Frigate
Level 41 "Myrmidon" Heavy Frigate

I was looking over the stats and didnt find Defiant as good as Myrmidon, so going MYrmidon direction.

So what ships are you other Privys considering.

Took all I have ever switched through.

Level 8 "Bermuda" Sloop
Level 16 "Corsair" Xebec
Level 22 "Corsair" Mastercraft Xebec
Level 33 "Stralsund" Mastercraft Frigate
Level 39 "Raa" Mastercraft Frigate
Level 50 "Hercules" Frigate or "Hercules" Heavy Frigate

Still using Raa for grinding though.
