This is a bit much for a first post but i dont have a choice. I just received my "brand new in the box 2010" Alien X today from AT, i love it so far. Problem is though, i'm not so sure it is a 2010. Is there anyway to tell? The limbs say "115" in white, which i believe signifies they are barnesdale limbs and the serial number is 0921963. Are there any differences between the two years? I became suspicious when the bow showed up in a Hoyt box with a string loop already tied. I inquired about the brand new bow being partially set up. Turns out the guy bought a bunch of bows from a shop that was going out of business and he wasnt the one who set it up. No visible marks from a rest or sight though. I'm just trying to make sure i got what i actually paid for. Thanks alot.
