I put a 2003 LR model on my LX about a month ago. So far so good. It has a plastic-like launcher arm that is very quiet when drawing a carbon across it. Sensitivity is adjustable depending on speed/bow weight. I have to admit that there is a little noise as the arm comes to rest from dropping. Setting the rest all the way back kept the arm from contacting the riser which helped with noise a little. There is still a little internal noise, but not bad.

Overall, I think the rest is pretty decent. I' ll let you know how it stands up in the long run.
