To the op.
Don't get too hung up on which camo you eventually choose. While some camouflage uniforms are better than others, they will rarely be the reason you are concealed.
Stealthiness has existed much longer than multicam.
If you haven't already, bone up on some fieldcraft. Understand the difference between concealment and cover from fire, etc.
Here are some links that are worth a look.

Always a good idea to talk to other players on the field about this too.
