What is the safest way to root a 5.1.1 so I can use the SD drive? There is no more "Move to SD" option in Apps Info like there was in 4.4 so now I am grasping at alternatives as my new Android is getting filled up while I have a fully empty 32GB SD drive just sitting there mounted and unused.  

Q:  What is the safest way to move these apps out to the drive?
