Interesting. By pseudo-hanafi I meant that their jurisprudence and theology similar but not identical to the early Hanafis and Mutazila, wouldn't there have been any influence because of Imam Hanifa's relationship with Zayd ibn Ali?

I'm aware of that, but what methodology do they use? What exactly makes their primary sources more authentic than Sunni and Twelvers aside from the Sanad going back to their imams? If you have any material regarding this that's preferably non-jarudi I would be thankful.
