TnBigBore: No - do not use them do not like them do not want one.
I have used the standard Du-Plex (fine Du-Plex) in my Big game and Varmint scopes since day one (the day Leupold patented the term "Du-Plex") when they started offering them for sale.
The "wide" Du-Plex can work but not nearly as well as the standard Du-Plex.
