Anyone looking for another amazing keyboard alternative check out HTC IME MOD that I found on XDA:
Code:

(It's a flashable zip that you install from recovery or CWM Manager so don't unzip it, place on your SD card and flash it.)
It has a lot of the features of Thumb keyboard and Cyanogen' Gingerbread mod keyboard (popup delay, keyboard dimensions etc) but goes one step further by adding gesture features among many other stuff.
I find the stock dimensions to be excellent, the keys are perfectly sized on the S2 whereas even once tweaked, Thumb Keyboard Keys are a bit slimmer.
Also I'm running Lite'ning ROM 6.1 now. Just installed over modaco and everything works. I had to clear Gmail data as it FCdas the included version was out of date then updated it via the Market as well as Youtube and Maps.
All going nice and smooth. Battery life is said to be really good on this so going to monitor as this may well be my permanent ROM if so.
