The setup you have shouldn't fly bad - pretty light, though. Try a 100gr head on those arrows to alter the FOC a bit - are you using wraps, by the way?
What is your draw length and weight and what spine are those arrows? Did you spin test the broadheads to make sure that they were straight?
I have good luck with the Axis nFused arrows with a 100gr broadhead (I used G5 Strikers but most of the better brands of broadheads should work fine), although I started with the ST Epics with Thunderheads (the Thunderheads were a little harder to tune - just took a bit more fiddling around but they worked fine.)
If you just want new arrows and broadheads go for it, but I might check my setup before I gave up on it - if it is the incorrect spine weight or screwed up FOC due to the light broadheads make sure that you don't make the same mistake with your new arrows, whichever ones you choose.
Depending on your draw weight and arrow length, you might be close to be under weight on your hunting arrows
