I use the QAD Ultra Rest-Hunter. I had the whisker biscuit and loved it for the ease of use. I was reluctant to go to a drop away because I thought it would be hard to tune and maintain but I also wanted to shoot the QS Speed Hunter vanes so the biscuit had to go. I heard a lot of good things about the QAD Ultra so I tried it and was so impressed it is now on BOTH my bows! Super easy to install and set up and very reliable and quiet. I even get tighter groups shooting it
