Congrats on the new bow. It's always a tough thing to accessories a new bow with all the choices available.
I'd recommend a Spot Hogg sight. I prefer the Real Deal sight but they have some new ones just coming out this year that are very interesting. They are built with all the right stuff and they hold up for years or at least they have for me.
For a good full capture follow away rest I'd recommend the rip cord or the QAD HD Pro.
Stabilizer I'd recommend a Stealth, they work better than most that I've tried.
Good luck and have fun with the new tool.
