I'm wondering if anybody would think any quests would be good for speed runs and tracking.

Generally the quests should be semi-well known and be built for runs and not breakers.

Ones that come to mind:

New Quest
Hidden Duality: Director's Cut (if not too overbearing)
Revenge 1 and 2

I don't know the newer quests as well, but I'm sure there are a few candidates.

Chime in.
