I have been struggling for the past three days over this.. I have EE3.0 overclocked to 710, a2sd going and generally everything is ok and has been fopr the past 2 weeks or so. I finally got battery usage under control and am kinda happy with it. But then I see Frisco and others posting about how nice XTR is being all snappy without SetCPU and is nice on the battery life. It would be sweet being able to move over with a2sd and dumping SetCPU. Then theres KaosFroyo.. everyone says it's pretty killer, but I would have to format my SD Card again meaning that my EE3.0 nand backup would be useless if I ever wanted to go back. I don't know.. would I REALLY gain anything by changing ROMs at this point? I was considering EE4.0, but I'm pretty pissed that under the changelog it just says 'Try it and find out'
