Whatever’s going to most closely reproduce the sound of an EMG 81/60 set with your gear. I’d be inclined to say Painkiller/Blackhawk/Miracle Man bridge depending on how dark to bright your guitar, amp, and cab are. Neck, you have a little more leeway, depending on which lead tone you’re more after (James it Kirk) and how important the cleans are. Hard to go wrong with a calibrated set, or slap a Cold Sweat in the neck and be done.
