Thoughts on current EL-34 tubes

I have just put my Jolida JD-1000P back into my system, and when I initially fired it up one of the tubes was obviously bad giving a good light show. I found this kind of strange as the amp has been sitting idle with no power to it for about six months now and the tubes Winged C Svetlanas were working fine when I took it out of the system. I replaced the winged C with another Svetlana for now and ordered up 8 matched Tungsol re-issues as I have heard that these tubes are some of the better of the re-issue tubes out now, what are everyones thoughts on current re-issue EL-34 tube available now.
