The top tail glowing red is a warning sign. It means you are shorting out on the coil. Washers or bending the wick will solve the glowing tail, but it won't solve the reason it was glowing: you have a short.
I've found, with my short experience, that wick torching does not solve everything. In fact, my last wick I did not torch at all. I soaked it 3x with juice, lit it on fire with a lighter (standard bic), and let it burn out. After that, I wrapped my coil. You want a decently loose coil, IMHO. Still touching everywhere, but not TIGHT. It should move pretty easily on the wick. Also, it is easier to adjust when HOT. Fire your coil, pulse power if necessary to not blow out the coil (burn through it), and poke at it gently, sliding coils up and down to get them all firing evenly. I got a 28g 9 wrap 1.5 ohm coil up and running in ~10 minutes last night on 500mesh doing exactly this, (no washers, no rolling paper, no bending the wick over). The coil glows red from the center out, and neither leg glows at all unless I run it at high voltage for a long time, (at which point the center is red hot).
