I enjoy the sounds the equipment is supposed to make (railsounds, freightsounds, etc) but dislike track noise. The ability to adjust individual components on Legacy, LC+2.0 and Protosound is an incredible feature. I usually turn down the engine and bell volume so I can hear the talking better. Occasionally we get a high-speed runner at the club, all tubular track. When that happens, volumes levels that are too loud for me at home are inaudible.
I've also come to dislike anything without a horn. It makes finding my train when I can't see it easier. The lower level loops at the club are at most 30% visible from any spot around them.
