I bought a TT Shakey the other day and put it on my Alien. Had it tuned to come up very late in the draw. I took it to my local shot to paper tune it and kept getting a vertical tear. The owner said it was because the rest wasn't getting out of the way in time. Is this true? I ended up putting a Bodoodle game dropper on. I am nervous that when it counts for the big buck I am going to shake the arrow off the fins. What is a rest that is fast enough other than the limbdriver?
