Hi guys. I have a habit of over thinking things, I got a new bow, and I need more arrows. My bow is a Hout Rx1 with 55-65 limbs. My original arrows are 27.5 inches, but they are long. I could do 26. I want to shoot a 150 grain broadhead. The Easton charts have me with a 500 arrow. Is this correct? I mean my original bloodlines I was shooting are 400, but I bought them a couple years ago when I was a complete noob. I'm just slightly less noob now...
