Very nice looking build. I've been experimenting with spacing my coils lately too. No problems working out hot spots as you mention, and I seem to get a smoother and more dense vape since I'm not drying out the cotton the entire width of the coil at once. The 'pockets' in between the loops feed the dry spots where the coil wires touch the cotton and it seems to 'recover' more quickly if that makes sense.
I dunno, not considering myself a total convert yet, but I've had good experiences with spacing my coils
