I gotta agree that EX must be the most reliable and biggest of bureau....
I live in NV and my pulls are as follow: EX-33 EQ-7 TU-4...BofA, Chase, Amex, US Bank, always pull EX. Citi would double pull EX and EQ up until recently when it now seems to pull only EQ (a relief of course). Barclays has always been TU for apps and CLI request. Wells Fargo pulls EQ here in NV.
