I know you said pick one but based on their merit and their activity all around the forum I'd say cryptoaddictchie(although he is already a hero member) and rikafip(a Sr. member) would be a great choice. there several members that have high merit but they are usually only active to one or two boards.
I appreciate the thought thank you for that but I think we should let zasad@ pick whose next in line for the interview.
and also we have some interesting suggestion here which should be a good options to pick from.
people that I will be very happy to see your interviews:
