I've been running Thrustmaster joystick/throttles, with CH Pro Rudders since day one, and I love them. Never did like the Thrustmaster rudders though, but the joystick/Throttle combo's have been fantastic for me.
When I re-signed up for Aces High this year, I picked up a cougar. After flying with it for 3-4 months, I still love it. You get used to the heavy pull after a bit. I've never noticed the chunkyness on mine at all.
There are a number of after-market upgrades, some of which, are very expensive. I've heard good things about them, but I'm too cheap/poor to invest in one at this time.
So far I'm completely happy with my Cougar. If you have the money, I'd reccommend the cougar any day. Use it with the CH Pro Rudders and you can't go wrong. If you want to cut costs, then the CH products would be my next choice.
