I like my SS coils neat and nice and tight. The myth about spaced coils working better with TC devices is just that. You can build a nice tight coil and as long as your connections are all good and your 510 is making good contact you're resistance shouldn't be jumping all over the place. A new coil might be .1 or .2 off but once it breaks in it's damn near perfectly consistent.
You can pulse dry burn, that's how I typically break in a new coil, to clean I just turn down the wattage a bit and let the coil burn off all the gunk for a few seconds.
