drilling balls that even slightly overlap is a waste of your money. make them different and you will cover a wider variety of conditions. i have never understood people who drill 5 balls the same and cant understand why they have problems and need yet another ball. different surfaces and layouts will serve you well. good luck! by the way both are excellent balls.
