Huh. I switched to the Zeus a few months back and have been pretty damn happy with it. Not as much flavor as my previous Cerberus tank, but it doesn't leak either. That said, I only vape around 40 watts or so, so maybe you're overdriving the coils?? I think they have some that are made for higher wattages. No idea if they wick faster or not though.
Good luck man, I hope you find one that works for you.
