I dont medic much, but I have the TRV and do like it fairly well. That 845 RPM is just fun to walk in and dakka a dude in the face with.
I play with the TRV with fore-grip and 3.4 scope in the field. if you learn how to compensate for the recoil it's good for mid range kills, sometimes a long kill is possible the SABR-13 for mid to long distance with advanced fore-grip and compensator and the TAR with laser for CQC
I use the T1 Cycler generally, and switch it up to the TORQ-9 if that gets boring. I'll break out the NS-11p whenever I need some extra range, but am probably gonna pick up the SABR soon and that'll fill that role much better.
