Verifying Schandorff:Grunfeld Russian System 7..Na6

Playing 1.d4 The Indian Defences(Quality Chess 2012) presents a wealth of repertoire ideas. Here let's take a closer look at the Russian System against 7...Na6 in the Grunfeld.

Schandorff  recommends 15.a3!? against the Prins(7..Na6) and analyzes an old correspondance game to support this idea.

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Qb3 dxc4 6.Qxc4 0–0 7.e4 Na6 8.Be2 c5 9.d5 e6 10.0–0 exd5 11.exd5 Re8 12.Rd1 Bf5 13.d6 h6 14.Bf4 Nd7 15.a3

Let us see the key game (#39 in Playing 1.d4 The Indian Defences).

Grunfeld Russian System 7...Na6 [D97]
Germany BFM corr BdF, 1998
The fast advance of the d-pawn is a double-edged sword. The pawn has a disruptive cramping effect but can itself become a target.

Position 1
Here I am proposing an novelty for black as an improvement. In the game black played 16...Nb8 but I think black can do better. What do you propose?
-Stay with 16...Nb8
-Play a different(better) move

Black to Play
