Hi, I just bought a pair of Youtek Prestige (non IG) off the bay. Got them and they look great, but I noticed right off the bat that there are no holographic stickers on either of them. One has a small sticker in the throat by the specs that has a single line series of numbers. The other doesn't. When I popped the buttcaps, the insides are different. One is completely black which I guess is foam filled colored black. The other I can see staples and 2 hollow chambers. Both the butt caps say TK 82. I really haven't seen or heard much about fake Heads. The hydrosorb grips look a little different and I suppose they could be made from different legitimate Head factories and that could be why the difference in the two, but I have to admit paranoia is getting the better of me. Any thoughts? I can try to post pics later (any help there is greatly appreciated).
