Thought I would throw this in from Skuzzy.
I had a telecom with him about my CH stick and rudder spiking a lot. I bought mine about 3 years ago. He told me he hasn't felt the systems from CH were ever the same since the company was sold prior to that date and that one of the best, if not THE best stick ever made was the Sidewinder series. For whatever reason, they lasted forever and just never seemed to spike.
Now, I know two people who fly with those and who will continue to buy them, used, on the internet until they run out and one of them is Batfink. The other, well, lets just say he posted a pic and gave away what he uses on an accident he isn't one to talk about his secrets.
Skuzzy can confirm the Sidewinder info vs the current CH systems
