I know the crappie don't seem to mind the difference.
And you're right, pvc doesn't show up as good, but the fish still do. We found a big wad of crappie on Palestine out deep and after looking real close you could see the PVC trees.
There are some PVC piles on Fork that always hold bass, and a lot of small PVC trees (2' tall) on Lewisville that are money. I don't think they bass care, especially if you put it in an area that is short on cover. The beauty is you can crash a crankbait through them with little worry of hanging up.
Keep the Lord in your heart and keep your powder dry.
