I had to leave this ROM for now. I am running it as the main ROM flashed with TWRP. It works well for some time, then objectionable lag sets in. Went back to stock JB leak and no problems, as before. The lag has nothing do do with Safestrap or running under internal emmc. I uninstalled SS and removed the app before flashing with TWRP.
Edit: OK, I'm back on Fuzion. I loaded the 24v HD_Tweaks_V1. I'll see how it goes. Installing smart actions did not fix the Motorola Voice Commands app. There are some interesting other alternatives in the play store.
Edit: Two days now after loading 24v HD_Tweaks_V1. The lag has not reappeared!
