I also have to vote in on Blackout Rom. I've used just about every 6.5 ROM and they are all slow in comparison. Since it has Sense 2.5, you really stop noticing what OS you are running. I've tried Mr X, Mighty, Neodium, etc... I keep going back to Blackout. If you haven't given it a shot, at least try it. I know once I did I was kinda shocked at how much more responsive the phone was. In fact Adrian has moved on to the incredible and was hoping a new chef would take on the 6.1 sense 2.5 reigns
