You aren't going to get good flavor from silica no matter what you do (IMO). Unless you maybe use ekowool. The silica being used in clearos is very uniform and the strands are close together.
Think of the wick like a filter.
juice gets sucked through but flavor molecules also get trapped in it and it "gunks up". That's why people say this or that device "mutes the flavor". No, it's not the device, it's the wick.
A homemade cottonball wick gives more flavor because it's not as uniform and the strands aren't as packed together. Therefore letting more
juice through the wick. Not just through the wick to the coil area, but allowing more flavor molecules OUT of the wick.
Which is why I think a tiny gap between the
coils would give better flavor than a tightly wrapped micro-coil. Not 100% sure on that though, just a theory, and probably not a noticeable difference either way.
Just something to keep in mind. One thing you could do is wrap the coil around the wick as loose as possible. Touching the wick but not choking it.
