No.
Ross isowned andmanufactured byBowTech, while Quest is owned by G5.
You may see that some of the older models look alike, because when G5 started putting its bows out, they basically took all of Ross's old stock (as they were then doing all the manufacturing for Ross) and simply put a "Quest" sticker on the limbs. They even asked all the then-current Ross dealers to send their bows in to G5 so they could put Quest stickers on them.
I assure you there will be no confusion in the lines moving forward with the advanced hybrid cam system featured on the new Rosses.
