Mark Beck testing of TwisterNock
 TwisterNock mechanically helps the spine of the arrow to recover faster. This will allow archers to use lighter spine(lighter weight) arrows with better accuracy, faster speeds, flatter trajectories and deeper penetration without changing the fletching, or preferred fletching offset.

Here is what Mark Beck had to say about it after doing some intensive testing of the TwisterNock:

Sling-on review by Crossbow Nation




Sling-on® can be added to any existing gun sling or bow strap.It rests on the top half of the strap and completely out of the way when it is not in use. Once you attach it around your torso it will hold your gun on your shoulder, so you can carry your game or equipment or just walk without having to hold your strap. It is adjustable for all sizes. It will hold your gun or bow securely on your shoulder even if you are carrying a back pack or tree stand on your back. Sling-on will drastically reduce the chance of accidental fall of the gun which could result in disaster.  Hunting Revolution also makes a Sling-on ® for gym bags, laptop bags or any kind of bag with a shoulder strap.
