Looking good, bro. I used to use two ViparSpectra V450s before my COBs and after my BlackStars. I recognized the light by the spectrum right away. I would just pay the extra $50 for a COB, but anyone dead-set on a panel for whatever reason, I always tell them to go with ViparSpectra. You don't pay out the ass for a panel like you do with Platinum, and despite the economy pricetag, it isn't cheaply made like Mars or Galaxy or Apollo (not trying to shit on anyone's choice, but that's my opinion.). So you should definitely be confident. You should get at least a few ounces if you do it right.
