Seems like a lot of wick for that catch cup, no? before I resquank I'll show the deck on my K6 - the airflow port is a bit lifted (i assume to prevent juice from leaking down the air hole when used how its designed.. as a standard dripper)
I wonder if there is any sacrifice in power to the atty by cutting down the surface area of the positive pin... seems there would be more internal resistance to the atty as there is less path for the power to travel, though I wonder how much and if it really matters given the size of the post

probably negligible as long as you aren't super sub ohming.
I cut the insulator on my tobh before doing the fatdaddyvapes center pin conversion, having the center pin conversion defiantly squanks a lot better/easier, and there is also juice left in the resivour as it doesn't drain from a low point on the deck (its probably 1-2mm above the deck on the center post).
