I have done a whole host of drop aways over the years, Trophy Taker, NAP Quick Tune, Rip Cord, Vital Bow Gear, etc...

What I have found is that the Vapor Trail Limb Driver is by far the easiest rest to get set up and keep in time.

I set one up on my hunting rig going on 3 years ago and have not had the need to touch the timing on the rest since then. I will probably have to replace the string and cables before the I have to touch the rest.

From an accuracy standpoint it really can't be beat. It is the best of both worlds with respect to accuracy and functionality.
Look at the competition target shooters. The majority of them shoot a blade type rest, why? The reason is it provides support for the arrow over nearly the entire power stroke. The drawback with a blade launcher is fletching clearance if you are shooting skinny carbons or have helical fletchings (like most hunters do).
The drop away allows for maximum fletching clearance but without the full arrow support as most rests are designed to drop away within the first 2 to 3 inches of arrow travel.

The limb driver stays up during nearly the entire power stroke, providing support for the arrow and is positively pulled down just in front of the fletching to provide clearance.

The LD is one of the few archery products that I am very passionate about because I think that it is technically superior to any of the other drop away designs out there.
