I personally thought the last DPR card looked tacky, I just got the new version also.
And I'm not so sure about cards being more flimsy than one another. I don't the difference, between my old and new, or any of my other cards with other banks, they all seem the same. Only difference might vary by bank slightly, like Citi using the holographic foil on top of plastic on the old DPR card and nothing but black plastic.
Either way, doesn't matter much to me.
