oh yeah, the loop from my profile pic failed within a week or two like W-L said. I've had other loops since then do a little better but it's been hit and miss for me depending on the loop. I think the best I've gotten was about 4 months but that was a huge loop with some valves and trickery involved. They're up to v4 now, they removed it from the actual title (no more Aurora 2) it's now just noted on the corner of the bottle. I've got some grey aurora but I haven't opened it yet, not sure if I want to go down that road again since I don't think it will fair well in the loop I'm building (too many 90's and fittings)
Also, Mick (Mayhems head honcho) said this recently on OCN
C'mon V5!
