You shold consider that actual CH sticks are "old" projects - probably the change to USB occurred around 2000, when 8 bits are almost stantart.
I think that secret of CH good performance in games is due drivers.
Look: Apparently Bob Church work for CH in this area.
Back in 1990's Thrustmaster F22PRO are problematic with pots - but pots used in F22PRO are virtually identical to ones used in CH... (I have both here)
then Bob Church made a new firmware - sold as upgrate- for F22PRO that cure these problemns.
To compare see this test (JoyTester) with Warthog:http://img853.imageshack.us/img853/549/joytes01custom.jpghttp://img69.imageshack.us/img69/7011/joytes03custom.jpghttp://img705.imageshack.us/img705/5669/joytes04custom.jpghttp://img845.imageshack.us/img845/286/joytes05custom.jpg
