Got the Mercury drilled yesterday, explained to my driller the reaction I wanted from this ball. What I got was exactly what I asked for, threw a practice game with it, the lanes where leftovers from the previous nights league so it was a good test of the conditions I would use it on. Started up the 10 board and the ball made a nice arc to the pocket, left a 10 pin, second and third balls left 10 pins, moved in 4 boards and swung it out to the 7 board and bingo run off 4 in a row. My driller had never seen a Mercury before as other than the Cell there has not been a lot of Roto Grip balls being thrown in our area.
Just wish I had taken the time to have this drilled up earlier.
