Specs: Left handed, 15mph, ~400 rev rate.
I took a different approach with the Guru Supreme, drilling 45*x6x40*, which places the pin just above my middle finger. Being left handed, this drilling has given me more opportunity to open the lane with the Guru Supreme! The down side is that I don't get the chance to play 4th/5th arrow often, but when I do need to, this ball has been a stud! I have the cover at 3000 wet sand so I can see the ball push through the fronts, begin reading in the mids and through the pins very easy. The great part (in my opinion) about the Guru line, is the core. When matched up correctly, this core just knows how to carry the energy through the pins and knock them all over. This allows me to be in a similar part of the lane as my Mighty, but the difference in drilling gives a different shape down lane.
I welcome anyone who has questions about the Supreme, or any other ball released by Radical Bowling Technologies, please shoot me an email and I will be happy to help in your decision making for your next purchase. ChrisHeringer@Gmail.com
