How do you go about changing the wick? What type of wick do you use? (For high VG I've heard organic cotton is good, or rayon, or are you just talking about regular silica wick material?) This is actually something I'm kind of interested in. My understanding is that the dry burn is done after the old wick is out, before the new wick goes in? Do you use any tools for working with the wick? What are good suppliers of wick for this purpose?
Hi for wick changing you may need a set of tweezers or very thin needle nose pliers. For stock setups all you need to do is gently slip the old wick out. Sometimes it may need a slight twist but it should come right out for the most part. Also discard the top wick pieces.
For rewicking I use rayon but using cotton the process is about the same. It does take a little trial and error but the learning curve is super easy and once you do a few it becomes second nature.
IRT rayon I use enough so that it squeaks through the coil. Not super tight but definitely making contact. Rayon will shrink per se when it gets saturated.
For cotton you want to use a little less than rayon but still enough to touch the coil when you slip it in (heh heh heh). Cotton will expand when it gets saturated.
I usually pick a piece of rayon off of the roll and gently compress it and aligning the fibers. I don't twist the entire thing only the first cm or so that it makes a nice point. Put the point in the center of the coil and gently slide it through working it a little so that it doesn't snag on the coil and break it. Same process for cotton. Finally snip the ends so that they are even with the bottom or base of the coil unit. Add a drop or two of juice to your newly installed wich and pop the chimney cap back on. Fill your topper, screw the base on and vape away.
Edit: It is a good idea to dry burn the coil once the wick is out to rid of any crud that may be built up on it. Simply fire the base with the coil unit and no topper. The coil will glow and that is ok, but don't do it for long as it could melt the insulator at the bottom or destroy the coil. What I do is dryburn it and then hit it with a little water from the faucet to rinse anything away. Dry burn it again to make sure it is dry and then proceed to wick.

HTH.
Since you are thinking about rewicking I'd suggest the possibility of recoiling too. We'll address that when you are ready!
Here is a rayon build that I had disassembled for some type of reference (nevermind that fancy pants coil, we'll start simple):

Interesting results from a different build I did the other day. I used some of that twisted 32 ga that I posted earlier in a T3S that needed recoiling. 7 wraps around 1.95mm drill bit yielded 1.4 ohms. Wicked with the usual suspect.
Results. This thing really vaped well! Surprisingly well! I went through the entire 3 mL in no time and the flavor persisted vice falling off a bit once full soak had taken place on the wick. Once I drained the tank I took a few photos.
To this date I have never had a coil and/or wick come out this clean. I usually kept the power at 6 to 6.5 watts and my older builds the wick would get "blacker" in the middle and this one seems like it was barely phased. This is after a quick rinse but I don't think it made any difference other than removing the remaining juice.
I am going to try something with chocolate in it (choc chip cookie) and see if it withstands. I believe that my old setup the coil was getting too hot too fast and it was burning the juice on top. This one doesn't seem to have that problem.
Yay! I now have a purpose for the 32 ga that I had set off to the side.
