I recently acquired an AT PRO from Kelleyco. I have yet to use it due to scheduling! I am curious as to how much of an advantage a larger coil will have. The standard coil is 8 1/2 X 11 and the only available larger coil is 9 X 12. Can another 1/2 X 1 increase in size really make a difference? Is there much difference between a double D and a concentric coil?
