I’m about to buy a CT and it comes with one Real Course Video…
Any suggestions as to which one??
From my experience, pick one that was filmed in the middle of the field, not in front. I find it hard to stay motivated and ride long with no other cyclists around (like the KONA video) but I find I can ride for hours with people around ( IM Canada, Wisconsin, NYTri, etc). Just my opinion…
Enjoy… 
I have IMAZ and IM Canada.
IM Canada is far more enjoyable.
