I agree and most 10 to 1 will agree that the Limb Driver is hard to beat. It's at the very top of the drop away category and one of the easiest to install.
Another I'd be interested in is the Kazaway from Vital Gear. It's a sort of full containment drop away. It holds your arrow when at rest and releases it as the rest rises. I watched a friend of mine shooting this rest at the NE gtg and I was impressed.
Another is the Octane Tripwire. Excellent rest.
I do currently have 5 Limb Drivers but wouldn't hesitate ont he Kazaway or Tripwire.
