Question: Is the new stock of fused quartz tanks provided by a different source? I ask because I just got 2 in on Friday after breaking my original and it seems like the inner diameter of the glass has changed slightly. The original didn't budge at all when it was on the atty and needed a little finesse to get on/off but this new one I currently have on spins super easy and slides up and down with almost zero resistance. I've accidentally moved it up the atty a few times while re-coiling this morning and got a little juice in the tank protector threading. It doesn't leak, but it caught me off guard. It's not due to juice on the o-rings lubing it up as that didn't make any difference on the original. The good thing is it makes it super easy to take the tank off. The bad is that it seems less stable. Since it's not leaking it's really not a problem, but like I said it kind of caught me off guard when it went on so damn easy.
