Learning the game with LWAMI should work well.
You'll have updated 3D models and more units represented. Just remember, LWAMI came about when the player community started to get bored with the stock game.
Your sonar displays have some "blinders" added to them. This will change some tactics, for example how you track contacts or use your towed array.
I can make arguments both for and against using LWAMI to
learn the basic game, just stay aware of those blinders as you gain experience.
