Just replaced my X52 Pro (I broke the pinky modifier) with THW and so far very happy. Build quality is light years ahead of X52, just needs a little time setting up my profile.:)
I use the same flight stick as you Predator and find the best way is to use the in-game set-up. Saiteks own software can be a bit....flaky.
I don't think that the throttle slider can be used for zoom. I just use the wheel on the throttle.
