Yeah, the Carbine has worked really well for me, I haven't really seen a need to stop using it. Hemlok BF-R is alright, but you had better hit and kill the guy you're shooting at with your first 3 (or 5 if you have Starburst equipped) round burst, especially if they have an automatic. I haven't tried the EVA-8 Shotgun yet, but I do have it set up as a custom class, so I may pull it out and give it a whirl, especially to get some of the shotgun burn cards.
