Hello. I have bought 2 raquets K-6.1 95 from 2 different retailers. I have noticed little difference between raquets: 1. On 1st raquet above word "[K]Factor" i see "®" but on other stick there is no sign of this symbol. 2. On side part of raquet i see "TM" on 1st one and "®" on another. 3. "Made in china" appears under "designed in the usa" near hologram but on another stick this word "made in china" hase written on another place. Painting seems to be same but construction of frame a little above grip is different. And difference is in what one frame little more rounded than another. Both frames has come with holograms. Can you please tell me if they're genuine or not. I heard what wilson have some problem with TM of [K] symbol. Maybe all this happend because of that? PS. If it will be needed i can make some photos. Sorry for my english.
