Good luck with your search. It's extremely important for people who work with regs to understand how to navigate them. If it's not already covered in the training, add "WHEN to read the reg." I've seen many problems that stemmed from bankers who relied too heavily on the softer support material (summaries, training manuals, commentaries) and bypassed the reg. Support material can be very helpful, but it's never a substitute for the actual words in the regs.
