With kanthal I think it's just a matter of preference.
With kanthal I prefer parallel 28ga micro coils
With Ni200 I prefer a single work hardened 28ga nontwisted spaced coil
You're way more sophisticated than I am, Willie!
But I have to say I was intrigued when I saw a tutorial about winding tightly spaced kanthal coils on a screw (or was it a bolt of some kind?). Really neat coils. Can't remember where I saw it...
