As much as I like solicited consensus (ha!), don't do what anyone else says. Just go and be. The entire event is the real deal.
50 plus Masters worth of experience says otherwise-very often escorting first timers,
The Masters has gotten increasingly more complicated to spectate over the years-from parking, a long hike in if you arrive past 9 AM(best to have an uber or taxi drop you unless very early) and ever increasing length of holes creating spectator logjams.
It's still top notch and still The Masters(though I would argue The Open is a significantly better spectator experience).
You can still have a great experience but...
I would most definitely have a plan
For example, being a student of the game/swing as you are, hole #11 tee is the one place you are guaranteed to get a great closeup view of driver swings.
Plan where to stop and grab a snack-know where the spectator favorite players are and don't hit a concession stand near their gallery.
No phones-leave them in the car-don't check them at the stand. Use the provided free phones if you must be in touch.
Not sure I buy the walking the course backwards thing-especially if this is the only time you'll see it.
As a player, you want to see the challenge from where they will see it.
