The Mega Friction also works well with bowlers with lower tracks. I have three Mega Frictions, only two drilled, and the one with the pin above the ring finger cg kicked right a little and lightly polished is a great THS ball. The ball plays down and in and swings very well. So not only for bowlers with high ball speed and lane conditions with a fair amount of oil.
