Thinking of puting one on my Switchback. Any thoughts?

go for it

Do it. You will not be dissapointed. I have one on my Outback. Have one on my Q2. I had one on my Diamond. It will be on every bow I own from now on.

What exactly are these things?

I have a Muzzy on my Dually and it's the best rest I've used to date .I ran over my bow a few week's ago and the rest was the only piece that wasn't crushed ,so it's definately a tough reast and will take a ton of abuse .

Here ya go, boone and crockett; I think this will explain it for ya! http://www.huntingnet.com/forum/tm.aspx?m=1687790&mpage=1&key=muzzy&#1 687790

In the pictures it looks like on the Mathews bows that have the roller guides that there is little room for your thumb on the grip in relation to the arm for the drop away. I am thinking about buying one but would like to make sure there is no chance for the arm on the rest to hit your hand. I shoot with an open hand. Thanks for any input.

You won't have a problem with that ,I shoot open handed as well .There's lot's of clearance .

I have one on my switchback. I have had one on every bow I owned the last 5 years. They are hands down the best rest on the market IMO.
