the most understable disc

Sonic is also extremely understable

Discraft stratus is the most understable mid I've ever seen...

That is what I use for my understable shots 200-40ft. For inside 40ft , I use a very soft, flippy Soft Magnet.

If you want ridiculous understable try an Optimizer.

You can actually flip an Optimizer by putting it too hard, no joke.

elite z eveanger ss, very flippy when throw flat and hard... it was too flippy for me so i traded it for a force

Discraft Phantom

I second the Phantom, also a old hammer works well for me.
