I love the Sense UI that my Aria came with and missed it on CyanogenMod. Since I could never get the Google Apps to work with the 6.1 RC I was tempted to go back to the stock ROM from HTC. Today I discovered an HTC Gratia ROM that is the same ROM as the one that comes with the Aria but with Froyo that someone at XDA Developers had ported to the Aria and that's what I'm running now. Love it.
