Well I've pretty much been flashing all day and have finally landed on this set up and I must admit I haven't had performance like it so far.
I moved from Andyxrom. V13 to Neat as I much prefer the look of a stock Rom rather than the blue theme of Andy X. There are no complaints whatsoever with this rom. Its responsive, fast and so far has suffered no lag whatsoever and I have literally hammered it all night since it was installed.
The Jkay settings are an excellent product to acompany this Rom. Well worth the £1.59 price.
Its hard to explain but everything is is just nice. Previously I have been having issues with a really slow play store, YouTube buffereing every 30 seconds, small crashes and force closes. I genuinely have had none of those and I've put it through its paces tonight mark my words.
For me one of the best settings from Jkay is "long press back button to close app running in foreground" Very useful when you have been browsing or tweeting.
I have a very poor signal where I live and work so my speedtest results are never ever good. My usual result is around the 750kbps download. After this install I reached over 2000kbps on each test. That may not be the greatest to you but for me in this location its a bloody God send.
I use Go launcher pro. It really fits in and is effortlessly cool if you get the right gesture settings etc.
I'm not sure how useful this is to anybody but after relying on posts from other people on here, I thought I'd throw my name in the hat to answer any questions people may have on these beauties.
