V Grip
When one stands relaxed with hands at the sides, it is not the thumb that is pointing directly forward, nor is it the forefinger. Rather it is the space (the V) between the thumb and forefinger that points directly ahead. The V Grip is built on this anatomical feature. The rod is held as for the Trigger Finger Grip, and then the thumb is slid a bit to the inside of the handle (to the left for a right-hand caster). This positioning allows the V between the thumb and forefinger to rest directly on top of the rod handle. In this position, the first bone of the forefinger and the end of the thumb rest on the upper, outer edges of the handle. Again, a very strong way to hold the rod, allowing the angler to apply plenty of pressure against the top of the handle to stop the rod dead on the backcast, and again to push against the handle with authority on the forward stroke.
This grip is used by both Wrist Casters and Arm casters, with the usual caveat for the Arm casters about not bending the wrist too much on the backstroke.
