It depends.
If you are the type of pacer who pitches it up, looks for swing, can hit a decent area for 4/6 balls and bowl in the 120-130s, you do very very well on Indian grasstops. It's why guys like Vinay Kumar, Kulkarlani, Binny, Sid Kaul are all basically gods in Ranji. But they aren't useful for Tests. Bhuvi is they very best you can hope to develop in these conditions, and as mentioned before, he is barely Test class.
Someone like Shami would (and did) tear it up there, because he is quicker than average and is a pitch it up outswing bowler. But as we see, he lacks consistency. Someone like Pankaj used to do well on the traditional Indian slow/flat track. He has accuracy, control, and is a hit the deck style of seamer so can extract a bit of life out of dead tracks. He also has good cutters. But he loses effectiveness on the kind of grassy wickets we see in Ranji now, even though he is more of a Test bowler than the guys actually taking wickets in Ranji.
Aaron won't necessarily go well in Ranji, because he barely swings it. Perhaps his extra pace will offset for that. In either case, it isn't a valuable experience for him. He'd gain more if he went over to play some County, or even some sort of decent level cricket in South Africa/Australia.
