Ok guys, these are awesome! Is the Plug too restrictive for you too? Use any OG peak cap or small bubble cap with your Pro! If you are tired of your old, limp tether here is your answer! This is the flexible brother to the Marble Spinner Hinges , except this one hinges using a high strength flexible material. It it works great with both bubble caps and directional caps. But in my opinion this Hinge REALLY excels with bubble caps thanks to the unlimited twisting action, and I believe the hard Hinge has the edge with directional caps with the easy twist and has the advantage of being able to hold itself upright. Both are awesome and can work with any carb cap as long as we can get the length.
