The ball using the  "monkeyfist" knot is a dream to handle  The leather is very soft which makes palming a breeze.  The balls are heavier which has a nice feel and no matter if the temperature is hot or cold, you can easily grip and manipulate these balls.  Additionally, they don't roll as far when performing cup through cup penetrations where movement helps the illusion. These "monkey fist" knotted balls are a great addition to your cups and balls routine.
