RE: Hoyt :Vapor Trail Strings
I doubt it came mis-marked from the factory. If you bought it new were the cams changed in the shop to accomadate your draw or were they twisted (not recommended by Hoyt) to fit you?
I had to have mine remarked after a cam change because of a 1/2" change. Always, repeat always, measure the existing strings and cable before you order them. Yes, that means stripping the bow but it saves heart ache later.
Good luck...and try calling the string maker, I'll bet they will swap them for you.
