In my opinion Before the bee patch the conference call was the best. But after the patch I'd say the norfleet is a beast and the unkempt Harold evn without the added power from the bee can still kill most enemies quick.
havent come across the norfleet yet and i spend every second on borderlands farming the warrior for the conference call 250+ kills still no conference call i have the intense unkempt harold and its a very good gun, im currently using the quik drawler badaboom and stopping lascauk along with the bee shield to farm the warrior and seem to deal with him easy enough.
Oh yeah evil smasher and infinity glitch is by far the best in the game but without glitching the infinity is a great gun it's the right relic and class mod you can dominate with only the infinity equipped
The CC is great but I like Miss Moxxi's Heartbreaker better. Badaboom RL (600k initial dmg). Slagga then PC smg combo and finally the Infinity for my pistol. Legendary Homing Corrosive Leech for my grenade as well.
