Since hes just refering to it as the hybrid I would assume its the one that COV sells, the bottom feed version of that atty has a somewhat weird connector design that has been causing shorts on certain modes(its believed that it was intended for a specific bottom feeder but afaik that has not been confirmed) they also offer a version with a sealed bottom post for dripping which I believe is what the OP is referring to. The sealed version will not cause short issues since it uses a more standard bottom connector but I am not sure if it will be able to feed(I assume
juice would have to flow
through the slots on the connectors and then up
through the air holes on the atty which may or may not work)
Personally I have used 3 of the bottom fed variety and haven't had an issue with a short yet, altho the atties themselves clog/fail a bit too quickly for me.
