Nothing to add specifically to your post but with regards to plugs, I'm going to use the Denso TT plugs. If I understand it correctly the ground electrode sees the "wear" on the exhaust stroke in wasted spark application.

Figure I will want longer wearing electrodes on both ends.

When I said "Platinum plugs have a shortened center-to-outer electrode path such that the spark is always on the platinum", I really should have explained it as a sharpened center tip and (sometimes) a protruding disk on the outer electrode. And, I was only commenting on wasted spark requirements. There's a whole different set of concerns for high boost/racing, and I'm way out of my comfort zone here. The amount of bad internet info on this is huge. As a reasonable start, try:

Confirmed that WR7DP's DO NOT play nicely with the WS/EZK116 setup. Breakup is gone with the WR7DC+'s installed.
