You should be able to use an arrow that has a spine number of 250, 200, 2000(Carbon Express, Redhead, PSE) or if using Easton, Victory, or Gold Tip arrows a .400 spine. At your draw length and poundage, if you were to go to more than 60 pounds, you would want to step up to the 350, 300, 3000 or .340/.300 in Easton/Victory/Gold Tip according to the spine charts. Your 30" draw length and poundage puts you on the line of one spine or the other(a pound makes a difference on the arrow charts). I would lean toward the lighter side of arrow spine(250/.400) as long as you don't exceed 62lbs and go up in the spine if you do. You will tend to get more out of the arrow(accuracy) with the slightly lighter spine and your set-up. You could bump up your broadhead weight to 125gr to add FOC and a minimally heavier arrow. 9-12% on FOC is great for a hunting set-up with more(12%) being better. If your nearest pro shop offers individual arrows to purchase, I would buy 2-3 of the lighter spined arrows and 2-3 of the heavier spined arrows and shoot them to see which does the best for your set-up. Get some 125gr field points too, to see if it increases or decreases accuracy. Be sure to check arrow flight and accuracy with each set-up and make a choice based on that. I have shot Easton and currently shoot Carbon Express and have had no complaints with either brand.
