Well I just got the STS system for my orion, kinda like it I must admit. I also purchased a teflon cable slide. The slide has holes for a drop away rest..alpine makes an affordable and rather nice looking and simple cable slide activated dropaway called the alpine whisperflite. Can anyone tell me anything about this rest, because if there isn't anything bad about it, I think 40 bucks is a reasonable price for a nice dropaway. thanks in advance.
