With a RTA a gunked up coil is sorted by pulling out the old wick burning off the coil with a few pulses of power, confirming the coil or coils are heating up evenly and strum until they are..
re-wick, prime the wick and reassemble..
More hassle than simply unscrewing and discarding an old coil and fitting another, But far cheaper as you only discard a penny or 2's worth of wicking material. and coils can last literally years..
on the other side a rta is more prone to leaking and/pr dry hits until the correct build/wicking style is worked out..
too litle or loose wick = leaks/gurgles..
too much or dense a wick = dry hits...
But once familiar with an atty and its optimum build, sorting out an exhausted wick isnt a major pita, and tanks like the kylin2 allow you to remove the build deck while retaining tank integrity and your unused juice.
some builds require finesse and an artists flair in trimming the wick. with the kylin2 and 3mm diameter coils wick cut to deck length need no trimming (assuming a wick density sufficient to provide just a little resistance when pulling cotton through the coil.. ) just take care to pack the wick evenly in its wick port retention. - or watch any utube build vid
Rta's require a bit of patience, and can lead to more vape kit with wire mandrills clippers etc, but you can also just buy pre wrapped coils and use those..
