From what I've read (and what you said previously) a "10-speed" branded derailleur is actually compatible (since they all have a 1:1.7 actuation ratio), just not if it's 10-speed Dyna-Sys. My other bike has Dyna-Sys, and now I understand why it feels "So much better". I had a feeling it was "pulling more cable" but had no way until now to quantify that other than just my general feelings and observations as a mechanical guy, without getting out my vernier.
