Some of the stats are a little off on that template, but all enchants/gems are correct. Here's what in-game character sheet says:
24,977 armor (devotion aura up, 61.12% reduction)
28.53% block rating
2014 block value
103.02% avoidance according to the handy avoidance macro (just barely unhittable)
First an foremost, I realize that I could get a [Lavanthor's Talisman] instead of [Item not found!], but since I'm still at 103.02% avoidance, I felt that I really didn't need more Block Rating and preferred the passive block value. A +90 STR Greatness Card would probably trump the GA-B since it procs more than once every 2 min, but I haven't been able to bring myself to spend 10k for a deck, yet.
Secondly, I chose [Tattered Castle Drape] over [Shadow of the Ghoul] for two reasons. 1) It hasn't dropped for me and 2) TCD has more BV and more stam. The only benefit of SotG is higher block rating, which again, I feel I don't need.
The char developer doesn't include the 50 stam from mining that I have. I also know that I'm missing a 41 stam gem. I usually use my 226 Malygos quest neck with a 41 stam gem in it, but I may put it in my boots, instead. Not sure. Regardless, it'd be a bit more HP for this block set.
As far as practicality... I wore this set and MT'ed Loatheb in Naxx25 last night. I think I was around 2274 BV raid buffed and managed to take a whopping 7700ish physical damage the entire fight. What fun. I'll post a WWS whenever we get it up.
