I agree it can be hard to get those quick corrections in, with the wheel
fighting back.
My non-FF LT wheel has been modified for more rotation. Just had the Formula
Force apart, and increased it as much as I can. It will not handle the 270
degrees (approx.) that I have on the Formula. I also have lighter centering
springs on my Formula, so it is effortless and smooth. The FF wheel has all
that spinning stuff inside it, and even with the FF turned off, it feels
strange.
The steering wheel nut was loose on my Logitech FF also, as I've seen other
people mention. I'll give it another go with the increased rotation,
tightened up, and some more FF settings.
