I've been practicing AAR using T16000m for one day and it was impossible to maintain connected.
Then I switched to X65F Force Sensing Stick and done full AAR in about 2 or 3 tries.
Conclusion is the ability of fine adjustment near the stick middle position is very important for AAR, IRL the stick is very long, so you can do very precise adjustment.
For DCS, you can use a Force Sensing Stick, a long Stick, or add large curve for regular stick, but large curve suitable for AAR may not be good for normal flying.
A good equipment made the AAR 10 times easier.
Using the regular game stick doing AAR may be harder than IRL, yes you can do lots of practice to overcome it, but i do not think it is about the real thing.
