I am currently G3.12 and right now I'm using the R201 Carbine, and I really like it, because it's really accurate and it does a decent amount of damage. I was using the Hemlock, but I didn't like the whole burst fire situation, even though I did a ton of damage. For example if a Pilot is jumping off a ledge to get away from me, I can't kill them with the hemlock, because they move to fast. But with the R201, I can shoot them out of the air. I would recommend it to anyone who moves around the maps fast and uses grapple. It also pairs very well the gravity star, because it has a high fire rate.
