This is just for information really, maybe it'll provoke a discussion. I want to show here why I prefer the buzzsaw trim on the top tail of the vertical wick. The first pic shows this "buzzsaw trim" where the wick is cut flush with the uppermost wrap of the coil, certainly no higher than the top of the posts. When you attach the lower tank section - which is the chamber and lower section of the chimney - you will see just how close the top of the wicks are to the chimney itself. See the second pic. Often we simply attach the completed tank and you don't see this.
If you leave a long tail on top of the vertical coil it will be both touching the chimney and obstructing your airflow. The same obstruction happens if you don't have a gap between the two wicks.
Obviously we don't want to obstruct the airflow, that's a good reason in itself not to leave a long tail. But there's another reason if you need it.
All atties create condensation which collects on the sides of the chamber and travels up the chimney/drip tip. We've all experienced a little juice in our mouths. With the RDTA there's a baffle on the drip tip to prevent spitback, which works well. It also blocks the path of condensate to some extent. This condensate can travel back down the chimney and into the chamber, it's visibly darker than your juice as it has been vaporised once already. I see this darker juice on the top of the posts and on the top of the wicks. This discolouring is many times worse if the condensate is travelling down the chimney and getting soaked up by the top wick tail. After all, wick does what wick does, right? The top tail will wick the condensate straight off the chimney.
It's not a problem that's particular to the RDTA, I have noticed with other atties that if the wicking is touching the side walls of the chamber, this section of wick will visibly darken. It's wicking condensate as well as fresh juice. Eventually the entire wick will discolour and the flavour will go off - you're effectively vaping on juice that's been vaporised more than once.
