Recovery on OMNI rom Mounts Ext.Sd and mounts proper USB Storage mod ( both sd and ext.sd ) . Plus supports 720p video with 417 MB ram on OMNI.
Tested on 2/7/2014 Omni Build. If it still doesn't work for you then goto System>libs> and del " modules " folder and flash kernel again.
Battery life is too good and can be compared to stock roms. Try changing governor to ONDEMAND and schedulers to NOOP.
My first post in development section , I hope I don't break any rules
