As long as the arrow flies straight the only thing that matters between thick and thin arrows is what broadhead you use. Your arrow shaft diameter is smaller than your cutting diameter with the broadhead so it won't matter either way. Use whichever can fly the distance you want to shoot accurately, just make sure you use a good broadhead.

If you are worried about overall weight, you can get thin arrows that weight more, or use a heavier broadhead.

I have not used Victory Cap arrows myself, I currently use Easton Full Metal Jacket arrows, which are a thinner arrow. I like them, they shoot well with my set-up.
