Newest Kit Acquisition PzKpfw.IV Aus.J Last Production

Just received the Latest Panzer IV from Dragon this week to add to my stash of Long Barreled Panzer IV's. It's their Panzer IV J Last production with Thoma Mesh Shields and 3 return roller configuration.  I am interested in doing an Ardennes Panzer IV J but this was a  later production tank as the Ardennes Panzer IV's had the 4 return rollers. Nevertheless Panzer IV Expert and Missing Lynx Axis Moderator Tom Cockle (a fellow Canuck) sent me a late 4 return roller Hull which was very generous of him. Now I can build that Ardennes Panzer IV J.  I have never built a Panzer IV and can't decide which one to start. At the moment I am leaning toward the F2(G) and finishing it in Afrika Korps colours.
