Cheers for response guys,
I have been stalking posts re sophia/diver probs and trying loads of different ways with the wick set-up. I have tried diluting with 10% Distilled water which helped but wasn't great.
I have tried playing around with tank level and 1/2-1/4 full seems best performance.
Its usually dry-ish hits sometimes real bad ones though!
I havent played too much with the juice control other than to open it right up, I will try reducing it see how that goes.
It does seem to help reducing the air flow.
I have been running Gorilla Juice, Goose Juice, Gizzard Juice, GVC, Bobas, and a couple of my own mixes. Bobas was probably worst, Gorilla is the only one that worked perfectly for a tank(undiluted in killer), Goose juice will barely work in sophia even diluted and havent tried that one in the killer yet. I know all of these are coil killers thats why I got a stack of coils, but the coils aren't eating any juice to get clogged up!
It have never had the Sophia work well, but the Killer has been fantastic on very odd occasions. Thats what makes this so frustrating.
