Yes I do,
e-liquid is vaporized in high quantity in cloud chasing; so much so that it isn't practical to hold enough of it at the coil to produce a dense vapor in any way without
juice movement in the wick medium.
Over wick and you get bad results, under wick and you get bad results.
Optimal wicking is such that
juice flow equals vaporization rate. There is a really fine line here that is easily crossed. If you want to improve the clouds you make wicking performance is certainly something that needs close consideration.
--------
Coil type and orientation heavily effect how you'll wick, and to some extent if the coil position makes wicking impossible that position can be crossed off the list as a cloud chasing position entirely.
---------
Wick material choice can have a huge impact on cloud chasing too, solid mesh and cable have a lot of ability to back as heat sinks, and that can inhibit flow; a sharp difference in temperature across the length of a wick helps flow, where as a more uniform temperature slows flow of liquids.
Remember flow tends to move from high pressure to low pressure, heat tends to reduce pressure and cold increases it.

Good luck
