I tried Kings 6.3. I didn't have any experience setting up an SD card for an EXT2 partition so that was a trial and error until I got it right. Once done, I installed it and it looks phenomenal, but the tiny font was too much for my eyes. One running there were frequent lags and I realized my SD card is the speed of a wounded snail. So.... I ordered a class 6 Transcend 8 gig from Amazon and will give it another whirl.
I did Mik's current 2.0 and it is stellar... not EXT2 needed but he has set up his most recent build to take advantage of that, I believe.
I am currently playing with CM7 N107 and have installed Launcher Pro Plus and Beautiful Widgets to get the most sense-like experience I could. I installed Tiamat's 4.0.5 kernel and Viperboys script set at -75mv. The phone is fast and furious and battery life is quite good... I also have custom screen brightness settings which have made a huge improvement as well. The phone has been on for about 5 hours and I've been modifying settings including flashing a couple of items and I'm at 81% left...
Hopefully soon there will be kernels for Sense!
