I would say you can get a good grasp on the build even if the guide is outdated. You'll need only to make some adjustments as putting more points into Solar Flare and keeping in mind the new itens as SSU Flail. Also looks like Hadriel set will be a good midgame alternative.
The problem with throw barb is the 120 ubers untwinked. At them (JD, Ureh come to my mind) you'll feel the need of some sort of reliable defense which forces you to spec into runemaster since getting a reliable amount of block without some charms is painful. This fact alone limits your possibilities...
