Change your plug wires out. I had one do the same thing(miss at mid load)in a almost new set. Would not miss at idle, or leady load. If one cylinder is missing, good chance it the wires.
Only other things it could be is valves, or rings, or head gasket, but you've checked compression. Or plug, but you swapped that around.
