Depends what you mean by 'snug'. You can have a coil digging into or compressing a cotton or silica wick (although it isn't optimal).
I've found if a fresh coil is resting against a fresh SS wick in any more than the slightest way it'll short. Which means that most of it isn't going to be touching it at all, even if it looks like it is to the naked eye.
