I have a TD and would not shoot another rest. I have had one lock up on me, however after reading the instructions it says to never do what I did to lock it up.

The new rest do fall faster, this helps in two ways. 1. It gets out of the way which makes fletch clearance a non issue. 2. It allows you to set the rest up with a less sensative setting, to prevent prefalling.
As for the clicking noise and your solution, it might work better on some bows than others. On my protec the launcher hits on the body of the launcher not on the prongs. So a peice of mole skin prevents my clicking. However I shot fingers and use a metal prong, so I can bend up the inside of the rest, and it does over time bend the metal up ever so slightly.
Thanks for the Review 5Shot
