Definitely Not Cloaked is a great group of guys and I highly recommend them.
If you are more interested in a smaller group in the Imperium, Sang-Froid is a PvP based IA corp on the ground floor. Founded by 5 pilots flying together for years forming our own democratic group. Mature comradery and understanding that people have real life lives and families. Based in USTZ and a few Aussies.
