best authority on Fed. rules?

[shipwreck]

O.K everyone check your pride at the door and please answer this question. Who would you
consider to be the best authority on Fed. rules? If you had a really tough question who would be
the one person you would want to answer your question? I have seen some names mentioned but
cannot remember where it was. The reason I am asking is because sometimes there are conflicting
answers on the boards. Thanks, Dave
