Those Perfect CMBs of Evisceration

Anyone on West have any experiences with those perfect Cruel Matriarchal Bows of Evisceration socketed with 2 40/15 jewels? I see them all the time in the trading channels and I'm almost positive that they are all dupes. But my question is, are the poofable dupes? Whenever I talk to the sellers, they tell me that they never perm the bow and it's never disappeared. Well, most people will say anything for a trade. If anyone knows for sure, please let me know. I am contemplating trading for one.
