That should do it. Very similar to my setup except I use the ST mags. Haven't shot and elk but penetration hasn't been an issue on WT's. Pass throughs on several. Antelope as well but they are like shooting through tissue paper.

I use Blazer's on mine fletched helical. I wanted to try them when they came out. They shoot the same for me as the Quick spins and regular 4 inche vanes did. They are very durable which is a plus. Smaller so less likely to knick them up shooting groups. As far as improving accuracy, I didn't see a difference.
