Your arrow spine will depend on your draw also.If you are pulling 28" and the bow is 50# a 2018 shaft with a 125 grain head would be pretty close for aluminum.If you wanted to shoot wood the best way to get the proper spine would be to order a set of test shafts.They would come in a few spines that are close so you could see which one YOUR bow likes best.Hope that helps some

I shoot a 50# Bear Kodiak Hunter. My draw is 27.5" and I seem to get good arrow flight using 2018 shafts cut to 29" with 140 gr tips.

Welcome Tim, it's good to see you here.

I'm thinking that the 2018 might be a tad stiff at 29". But then, it's different for all of us. Release plays a big part of what spine you'll need, as a stiffer arrow will compensate for a less than smooth release, as will large fletching and a weaker spine is needed for non center shot bows so that they can flex and bend around the riser as they leave the shelf. Length of the shaft, point weight, string material, draw length, bow design and brace height also play an important role in what spine arrow will fly best from your bow. First thing to do is get your draw measured with the bow and then get the bow weighed at your draw. Then I'd contact arrow fletchers that will sell you a variety of tuning shafts, say in the 45-50, 50-55 and 55-60 spine groups so that you can get zero'd in on closest spine and then tune the bow by adjusting brace height, nock point and so on, to get the perfect arrow flight needed for optimum accuracy and penetration.

If you keep the total weight of the arrow around 10g per # of actual draw weight, you'll be good in that department. Some like to go heavier and some lighter, but most seem to agree with the 10g rule.

I'd have to echo the sentiment of what your bow likes best. Try a bunch to get it figured out correctly. I followed O.L. Adocks advise on bare shafting and found that I was underspined. I'll suggest the 2018 with a heavier head, but also try a 1916 and maybe a few others too with different points.
This article was a god send to me. Sure it took me a few trips to the store and a bunch fiddling around but now I have no doubts about my arrow tune. Check it out:

What type of arrow do you want to shoot?
Wood, carbon, alum.

First, 50#'s is plenty for deer sized game. Don't sweat the heavy arrows. I use 3555 Gold Tips out of my recurve. I have 2 sets of limbs (45# and 55#). These arrows shoot well out of both setups. For aluminum, I shoot 1916's for the 45# setup and 2016's for the 55# set up. 2018's will work with extra heavy points. In my opinion, good arrow flight with 2 blade heads beats heavy anytime. Dick

You can buy woods arrows in some places for about the same price as aluminum arrows.

If you do shoot aluminum I would get feathers on them instead of plastic vanes, unless you have a elevated rest and are not shooting off the shelf.Plastic vanes tend to "bounce" off a shelf.

I've been using 2018s with Zwickey 125grn Eskimos heads for about 30yrs. I use the same arrows in all three of my hunting bows-
Quadraflex 60# compound, 55# Partner's(Palmer)TD &a 45# B-riser Bear TD. One thing I learned many years ago is that heavy arrows have much more killing ability than light arrows and they are always more forgiving. I also only use feathers on my hunting arrows- even on the compound.
