If you are good enough, the Vipera is amazing. I was a heavy armored, LMG Medic before but picked up the Vipera yesterday and now I am a light armored, SMG medic who dominates even more than when I used the LMG.
Viperia is awesome with a silencer, plus the shotgun is tons of fun to mess around with. You might think about putting a few points in electronics and getting the radar jammer too. --- MGO name: Thaddeus Crispin Glover> you.
