Agree with this completely. So long as the coil is set up properly, you shouldn't have a problem with shorts through the wick, regardless of where it is touching the atomizer. Keep in mind that with most atomizers the wick is touching the atomizer in the wick hole. A little bit of extra surface area touching the bottom of the tank is not going to hurt at all. That said, if I leave my wick touching the bottom of the tank, I tend to cut it at an angle to make sure that I'm not hydraulically locking the wick.
YMMV using a solid rolled wick. While solid rolled wicks do offer some advantage, including better wicking due to more surface area for capillary action and the ability to leave your pv/tank set on its side without leaking, I have moved away from solid wicks. I find that I get MUCH better flavor from tube style wicks. I do have to do the APV tilt to make sure that I've got enough juice to avoid a dry burn, but I prefer to vape tilted anyway so its not a big problem for me. Tube style wicks result in faster coil response, hotter coils, and permit the interior of the wick to actually provide a channel for vapor to come off the wick (more vapor!). Also, because there is much less mass of stainless mesh, you tend to avoid the flavor that a stainless wick can impart.
If you are tilting, might as well use what i use for one of my Gennies: 200 mesh, solid, very short so its basically just the portion above the deck and nothing sticking into the tank. Quick tilt and its all saturated. Wrap it with ribbon and amazing flavor. And because 200 is so little mesh mass, very quick to heat up. Give it a twirl
