Beaver eager,
I've just recently bought a CH flite yoke to run with the jeppy flite pro' software(approx'£100).There is not a whole lot to be gained over using a standard joystick,I also tried using a force feedback stick like your own, but this gave the worst results.The yoke offers a more realistic feel when held,but suffers from the same calibration twitchyness.It took me quite a while to find the right sensitivity setings.In fact I reckon that the lag and twitchy movement actually help to speed the scan up.
The jeppy flite pro' is just what you need to get your scan going again,but I don't know if the simulated a/c(c-172& a36beech) speeds are too slow for what you're used to.There is also the "Elite" software to consider but @£500 or so the jeppy is best value.
It will take a while to get used to,I use every day to keep my scan up to speed.Oh,and don't bother with rudder pedals.
