I'm using a MSFF2. My problem is somewhat related to Joe's I think.
The problem is that when I'm taking damage and I'm maneuvering, the stick is doing the "shake, rattle and roll", which I love the effect, BUT....If I take a fatal hit while the stick is not centered, I lose some FF, kind of half powered FF, stick centering weak in other words. Also, if I crash or blow up while the stick is not centered, I lose FF completely, and have to reboot my system to get it back. This happens now and then, because I have learned to center the stick and let go of it just prior to the crash. No ill effects on the stick FF if it's centered and not handled when fireball occurs.
