As tempting as it is to have a cloak for my merry band of science ships, I'm gonna have to say no. =) Let's keep the cloak unique to the Defiant, Galaxy-X and the KDF ships.
Agree but I have to say the ship that should have one as per canon (maybe soft canon?) is the Chel Grett since the Breen are known to have cloaking technology. I'm really confused as to why it didn't come with a cloak.
