I don't know if I'm the unique person here but I'll tell it, I guess the 06-01 kernel is more smooth than 13-01 version and I'm facing a bit laggy using WhatsApp and the latest Swype beta on my phone. Probably you will ignore this because ur phone is the "sky" but I think the flags of 06-01 kernel are better than 07-01, the first version, not the v2 or another thing. I come back to 06-01 meanwhile I see another changes in performance there. I'm not atacking your work or telling u what to do, I'm simply telling a opinion. Anyway if u want, I can test a new version or whatever...
Also I dislike the changes you made with Wi-Fi PM Mode when the screen off because sometimes I'm writing or doing anything and the Wi-Fi goes down and put on again without my finger pressed on any button.
su iwconfig wlan0
su iwconfig wlan0 txpower XX (where XX is the value in dBm)
