The Funky Finger is for use on both T.R.U. Ball Flex edition releases and the GOAT.
The 3 Finger - Funky Finger contours to your ring finger better as it has a smaller radius. This not only makes it more comfortable to use but it also makes it more consistent as your finger is in the same place each time. It is also set back an extra 10º compared to the stock adapter, this allows for complete relaxation of the hand without over rotation of the release aid.
All models of the Funky Finger have aggressive grooves in the finger bed to ensure your fingers don’t slip while at full draw.
