My order of preference would be either 4 > 3 > 1 > 2 or 4 > 1 > 3 > 2. #2 has poor shield coverage, and #3 may be susceptible to RF ingress at the capsule unless you connect shield to mic case. #4 has lowest shield resistance but also somewhat higher parasitic capacitance than #1, I imagine.
I can see a few potential problems here:
1. While the capsule is quite hot, you would still want to have a quiet bias supply. How do you safeguard against devices with noisy bias (more common than you might think, onboard audio for one is notorious)? Right now you don't. I would contemplate adding a battery and some active circuitry, either in the microphone body itself or as an inline box. This could enable driving substantially longer lengths of cable as well. Somewhere I had also bookmarked an article on distortion compensation for JFETs that may be applicable to electret capsules...
2. What sort of interface will take a consumer electret? It would pretty much have to be a consumer soundcard rather than the typical USB audio interfaces for home studio use with their balanced XLR mic inputs. With extra electronics, you have a chance of accomodating both.
This being an omni capsule, I am guessing it is for some sort of measurement application? Not sure how the recorder would be used in this context though.
