I have a Cold Sweat neck and Miracle Man bridge in my 2011 SG Standard at the moment and it is pretty nice. I liked the Cold Sweat bridge too but it is brighter and lower output. The MM really does hit those pinch harmonics pretty hard, as its reputation led me to believe.
On the other hand I had an A-Bomb in the same guitar at first and never liked it. Switched it out after persevering with it for six months. Not even remotely versatile, just one aggressive tone all day long. Reminded me of Sepultura, Possessed, and Poison Idea all rolled into one. On the other hand it is great in my Explorer, quite versatile. You need to get the pickup that will balance the EQ of the guitar. SGs are all mids acoustically, with not a lot of bottom end.
Other pickups I've used in SGs that have worked very well: A-Pig (with matching neck pickup) and Stockholm P-90. If you were to use the Stockholm bridge in an SG I'd recommend the Supermassive neck to go with it.
