Hey I've spent the afternoon sorting out my phone. (Good procrastination for exams) and I've decided on running CdTDroids CM9 rom rather than a jellybean based rom which I have been using for the last few days. I'm also running Siyah 4.15 so both are stable (Sick of running experimental/nightly builds). I've done a few CPU/GPU tweaks as advised from threads on XDA so i'll see how those go over the next few days. I'm basically looking for something that has no lag, opens apps such as messaging and dolphin fast etc while still being somewhat good on battery (last around 15-20hrs of daily usage) so basically from when I wake up to when I goto bed. 

Instead of testing a multitude of different modems, I thought I'd ask here and try find something with good performace on Telecom while still keeping batter usage in check so no wake-lock issues or apps getting stuck etc.

Thanks
