VBM- I' ve used the trap door,mirage, and the new drop zone rests on my Legacy. I have also used many of the popular prong style rests as well. After all my experimenting the drop away rests are the best in my opinion. I feel accuracy is much better when there' s no contact with the rest. Of the drop aways I' ve tried it' s between the mirage and drop zone. I feel like the drop zone is quieter and easier to set up so it' s my first pick. So far it' s been very dependable and works great. There has been some quality issues about the string coming loose on these chat rooms so I' m a little concerned about that, but so far it' s been perfect. FYI, the mirage had to be sent back to GK for problems once and then right before hunting season the aluminum bar that holds the rest broke and they had to send me another. I' m told that bar is now steel but it just goes to show that any rest can have problems. The prong styles are definately more bullet proof but I think the drop zone will be dependable.....
Good luck
