First of all, congratulations! It's literally amazing how much better a new bow feels when you make that big a jump.

In the 30 or so bows I've owned over the last several years, I've ran through a LOT of accessories... the Matrix sight would beat the very bottom of my list. To me, there's WAY better out there for cheaper: Spott Hogg has some of their entry-level sights at a nice price point with MUCH better quality, Extreme (just make sure you get the new supported pins and pin guard with it if you go that route), or even Sword or Viper.
