I've owned a few TM sticks and had a CH Force FX/Pro Throttle setup as well as a Saitek X36 and the Cougar beats thems all hands down no contest whatsoever.
The springs feel light to me, they are 18lb and you can move the stick with just your thumb without much effort, remember the heavy weight of the handle (and it is heavy!) makes it feel lighter than the springs suggest. You can use your analogue pedals and plug them straight into the Cougar not only that but you will be able to program the axis on the rudders through the Cougar software.
The build quality on this stick is quite amazing. The all metal construction gives this stick a good solid feel. The buttons, stick, hatswitches and base are all metal. The buttons have a very good feel to them, its hard to describe but it does'nt feel at all like any other stick I've had. Even the old TM, CH or Saitek sticks were either too 'clicky' or too 'mushy' feeling. The hat switches on the Cougar...well they just feel 'right'.
Programming is a breeze. I recommend this stick to others and one guy was a bit put off when seeing a profile I had done but once I showed him the basics he was up and away doing his own profiles. I did'nt pick up the manual for almost a week and only did so to find out more about the advanced programming available. The help wizards are straight forward and idiot proof and using them will see you with a working profile in no time at all. While it may not be as easy as say the point and click style of Speedkeys or Saitek's SGE software it's easy enough while also giving you much much more programmability over any of the above sticks. You can map hat switches to axis (there are 10 available) you can program thestick and dramatically alter the way each axis behaves so for instance you could press a button on your stick to set you up in landing mode or refueling mode (if you like Falcon 4.0 for instance) and upon pressign that button the axis of the stick either become more responsive or less. The mousestickcan be used very effectively as a mouse or a mini joystick, it feels very much like one of those mini sticks on an analogue gamepad.
As for quality, wel laround 10 years ago I bought my first TM stick and its still going strong today, my other TM stick lasted me 6 years so combined with the all metal construction I'm not planning on buying another stick for some time. Support is very good through TM's own forums and the Cougar design team hang out on Cougar World which is run by the guy that wrote the Cougar software so help is on hand and very quick.
So incase you wondered YES I do recommend the Cougar
