The Shrike really should be reclassified as "Heavy Raider", given that it is more comparable in size, mass, and combat capability to Frigates than other Raiders. At our table, we don't really consider it a "proper" Raider, though most of us seem to quite like the ship all the same.
Its niftyness as a ship has led me to include some scattered, surviving remnants of the Meritech people into our campaigns, just because I like the ship so much (well, that and wanting to bring back the whole void-scavenging human gypsy concept/40K version of Strigany).
Needless to say, my players now have a Shrike in their fleet. They had two, but one was captained and crewed by npc Meritechs, who have since gone AWOL doing Emperor knows what.
