I've just recently ventured into the custom ROM/kernel thing. I've only tried a few and I'd like to know what you guys feel are the best for you. I know everyone will have different answers as certain ROMs will fill certain needs and everyone is different. As far as ROMs go, I've only used Fresh and CM6. I was on fresh 126.96.36.199 w/ netarchy-toastmod-188.8.131.52 CFS for about 2 weeks and I felt it was very stable and my battery life was great I just flashed CM6 today and I'm not sure how long I'll be on it since it (obviously) doesn't include 4G and I'm in a 4G city. Having said that, I have improved my quadrant score by about 700pts using CM6 w/ snap 7.6 turbo. What are you guys running and why?
