I have both a Trophy Taker and a QT4000.

I agree with everything that's already been said about it. My only dislike was the noise made when drawing an arrow across it. My TT is dead silent.

The man who works at the pro shop that I frequent (a highly experienced bow hunter and competitor) said that the only thing that he didn't like about rests that tie into the cable slide is that moisture can sometimes make them "stutter" and cause the rest to fail. He said that he has seen it happen often enough to keep him away from those types of rests.
He sells both and has no interest in swaying the customer one way or the other from a sales standpoint.

I switched back to the TT for it's utter simplicity, ruggedness and silence.
My bow shot very well with the QT4000 in place.
