There are many factors that go into selecting an arrow. There is usually a range of arrows that will work for your setup in a range of prices.
Some considerations are:
- Spine
- point weight
- length
- fletching
- cost
- diameter
- overall weight
A good place to start is some of the on line cataloges. You will get an idea of what is available and can make decisions on how much you want to spend. Then go to the manufacturer's websites to figure out what spine that you will need.
Of course, you will need to figure out what you plan to do with your archery. Hunting, target competition or simple plinking can lead to different arrow selections. Not better or worse, just different. However, some arrows can be good choices for all three. It just depends on which direction archery is taking you.
Good luck,
