When I bought my bow, I was pulling 52lbs. Now I cranked it up to 64. I was shooting 2213s with the lower weight but I am unsure if they are enough for 64 lbs and 100gr. broadheads. What do you think?

What cam type and arrow length?

If your arrow is longer than about 25 inches then it's probably not stiff enough. How long is your arrow?

shot a bare shaft at 20 yards it will tell you, only if your in true center shot. If you are in true center shot, just take a shaft without fletchings and let it fly. If it hits left they are weak. You might want to try like 10 yards so you don't miss the target. This assumes centr shot and good form, especially bow hand placement.

I have a single cam bow and the arrow length is 28".
