I think that the nexus reception isnt bad, its just that it doesnt fake the number of bars it has like the iphone does. The Galaxy Nexus had the same issue, the update basically does nothing but mask it the real reception.
Back to this, hows the OS with battery?
edit - the link will be in the op, the rom is rooted, and comes completely stock.
There are no radios or anything included in the rom, so it makes sense to go and fastboot flash those on your own for best results
