Wow...first impressions of the new tube and atty are really good. Been through half a tank so far and the atty is staying much wetter and there are bubbles coming out of the atty just like a carto! I never noticed the first attys doing that. No leaking, but the atty is a little spitty which I'm sure will settle in a day or two. This is much improved over the previous atty's which weren't bad to start with, I went with the 2.5ohm this time for the Opus which is working out very nicely so far. I'll post more after i've had a chance to break it in and work it for a while, but so far its a nice improvement.
