With airflow, undercoil is a safe bet but many vapers have amongst their favourite flavour bangers an RTA that employs side airflow inserts, for me the Bishop blows “most” undercoil airflow RTA’s away. This also has the air angled across the coil which if the original Zeus is anything to go by gives air coverage to the coil more evenly.
As for the rest as mentioned in the thread with Holy Atty they always have something a bit different with their designs which pre-release most like you have major doubts about but with every other release the doubters have been proved wrong so until vapers are actually using this nobody knows for sure but my bet is on those delicate pins do a cracking job and the “thick” O-rings used as “springs” in my opinion are quite genius. My guess is they first tried a spring but those O-rings worked much better!
