About a month ago I saw an article about Griplock Thumb Inserts.
From what I have learned based on looking at their website this
product could be really valuable to those of us that have to
continually put tape in or take tape out of the thumb hole. Have
any of you bowlers out there ever used this product? If so, what
was the cost? So far the only place I found anything about them
is on their site. If any of you want to investigate this product
their site is http://www.griplocproducts.com.
