CB from what I have heard, is great pretty much anywhere, which is one of the reasons why Marines have adopted that as their new colour. But if you are going for OD, than definately get the Phantom, the OD colour is much more floral and verdant, the MilSpex is dark for some reason, it may go well for ACU set ups, but for what you are going for, I think the Phantom will suite your needs better.
