It looks like the GM choice these days is Na6, headed to c7, to support b5 if white allows it, and add pressure to d5.
A Benoni Line

Some of my games transpose into the position below. This is by choice I like c5 a little better than Nc6 and e5. What do people think as far as the strategic plans from this position.
One, I consider to exchange the bishop via Bg4. For one the f3 knight covers d4 and without it black gets better control of that square. I'm not sure it makes a huge difference on white's idea to play e5. Plus the light squared bishop doesn't have a lot of good squares and on b7 it could be quite idle.
Besides dealing with the bishop there are the questions of how to deal with e5-e6.
If black is slow can white look at Ne1 f4?
What are black's best bet for queenside counterplay Nd7-Nb6 a6 b5?
