Actually X, the T.E. comes stock with HAPP parts, though that doesnt mean what it once did lol. I suspect alot of people will be swapping out the HAPP parts for I.L.
But try it out at least, not all HAPP parts are garbage. While it is true they're overall quality has taken a hit since breaking away from I.L. and moving they're manufacturing to China, you never know, you could get lucky.
Ive actually started using the HAPP Super joystick in my MK sticks and I have to say I love them, even over the I.L. (Heresy I know lol)
But Ive noticed my execution improve since I started using them.
