I am going to get a better probe this month and have a simple question. I use three coils with my ET and to save hassle I have them mounted on three separate upper and lower shafts. Changing coils is just a moments effort. From what I read Sun Ray would require three new upper shafts to retain this simplicity of use? Is there any way around this? I think the answer is going to be, nope, but thought I would ask just in case. Thanks in advance, Terry
