Is there a sure fire cure all to keep the balls from popping out of the leather pockets? I have tried chalking the pockets, which helps a little, but gets messy quick. I have been told that saddle soaping can help a lot but can also stain the balls. It doesn't happen often, but usually at the wrong times. It makes sense, leather tip or leather pocket equals friction. Live and learn and go plastic next time? Or will they eventually break in and get better, or get worse? Been over 5 years...
