It saves me time from having to set the topologies up myself, plus I don't know of any other CCNP-level workbooks out there other than the official Cisco ones and Simplified. I've also heard that VIRL now does L2 but L2 devices count against the 15 device cap. Is that true? If so you may still need to use IOU/IOL over VIRL for CCIE labs.
