Every time I do Prestige Mode I try and use new weapons (I'm on 4th prestige), but I've had more or less the same types of classes each time.
My current ones are:
Dragunov
Dragunov - Red Tiger Camo
-No Attachment
Desert Eagle
-No Attachment
Bandolier
UAV Jammer
Iron Lung
Frag/Flash x 1
M4 Carbine
M4 Carbine - Digital Camo
-Silencer
M1911 .45
-Silencer
Bandolier
UAV Jammer
Extreme Conditioning
Frag/Stun x 1
G3
G3 - Digital Camo
-Red Dot Sight
Desert Eagle
-No Attachment
Bandolier
Stopping Power
Steady Aim
Frag/Stun x 1
AK-74u
AK-74u - No Camo
-Red Dot Sight
Desert Eagle
-No Attachment
Bandolier
Stopping Power
Steady Aim
Frag/Smoke x 1
G36C
G36C - Desert Camo
-Red Dot Sight
Desert Eagle
-No Attachment
Bandolier
Stopping Power
Deep Impact
Frag/Stun x 1
My favorite is the M40A3, which I think is the best sniper as it is most accurate. Recently though I've been using the Dragunov. The semi-automatic capabilities combined with low recoil and the ability to kill in one torso headshot has made it my choice for sniping recently.
Edit - Updated. I'm a 44 in 5th prestige now.
