I've played courses just over 7,000 yards where I felt like the length beat me up and others the same length where I didn't seem to notice very much. Never played a course 7,445.
For me it seems like the ones with a lot of extra yardage on par 3s and some 4s with relatively normal par 5s are the ones that "feel very long" while I'm playing them.
If the par 3s are reasonable (under 200 yards) and the par 5s are very long I don't seem to notice as much (except that the par 5s are 3 shot holes).
Based on that I'm not sure what Augusta would feel like. Seems like some of the par 4s would feel like par 5s but the par 5s would feel about normal. The par 3s would actually seem a little short compared to most except for number 4.
The members should let us play it so TST community would know.
