Third party sounds

Folks

I'm exploring my first foray into third party sound packs, one to replace definitely wrong generic sounds and another for an OK but might be better. Is there anything I need to be wary of with TSS sound packs? I'm a bit torn with the QW sounds - not sure if the TSS one is much of an improvement and it's a bit hard to tell without trying. (and since I don't know how it works, might screw up the plane specific sounds like the cabin manager talking in the background)

Cheers

Mike
