bolts for the Grizzly?

[76chevy]

which bolts would you recommend as an upgrade from factory bolts?

flat back nocks and prefer to use lumenocks on hunting arrows.

Bro, I use the Diablo and have driven it length wise through a 425lb hog, killed two hogs with one bolt on a double pass through, and they shoot zero for me.

You can lightly spray the bolt and fletchings with reflective paint which shows up with a flashlight but most of my shots are pass throughs so a lighted bolt would not matter much for me.

I have recently switched over to Spynal Tapp arrows (powered by black eagle). They can be purchased from Southshore archery. Other good arrows are black eagle Executioners or Zombie slayers.

Factory arrows are ok but to take your bow to the next level go with black eagle.

I have found 18" executioners with 110 grain inserts to be a perfect match for my Matrix 310 which is the same as your Grizzly.
I have used Executioners, Spynal Tapps, and Zombies with the Matrix 310 and Matrix 330 with very similar results.
The spynal Tapps and Zombies are a little stiffer than the Executioners, but the Executioners are plenty stiff enough for the Grizzly and are very impressive when it comes to accuracy.
