Are there any alternatives for scoping the primary coil on a COP system other than using a low amp probe? I'm guessing backprobing doesn't work since the ignition control module is built into the coil and it receives a digital signal. Am I stuck looking at secondary or current ramp on the primary?

Check out the General Technologies TA500. This tool is quite inexpensive (for its incredible capabilities) and very flexible. Perhaps not for the DIY set, but there's no probing involved and it allows you to do coil-to-coil comparisons in seconds.
