My general criticism of this analysis is that it's presented as SoB vs. SoV, whereas in fact the underlying question (I believe) is more about looking for a maximum threat setup. So a couple of specific points I have with the OP:
The gear set presented is *extremely* long on mitigation and short on threat. I understand that fits the OP's biases, but in an analysis looking at maximising SoB it makes sense to look at using more threat-oriented tank gear. At the very least, not capping hit and dodge-capping expertise is going to lead to a refutable conclusion. Anyone who's willing to actively damage themselves while tanking is going to be happy to lose a little mitigation to get some threat stats.
Second is the spec; again, I think using something reminiscent of the old Imp SA build (
0/51/20) is going to be the preferred SoB spec. (Some of the points there are arguable, specifically lack of AD, DG, GbtL. On the other hand we have no quantifiable data for *either* threat or mitigation talents so one has to start somewhere.)
I have no love for SoB, but I'd been intending to make a threat spreadsheet (more accurately, a prot DPS spreadsheet) anyway, so this might spur me on to it.
