I am new at this. I have an older bow 70 lbs. I do not have any arrows. What is a good arrow to learn to shoot with. Inexpensive is always good. I have a large backyard to practice. All i have is the bow and a new sight i won from NAHC. Any help would help. SDhould i buy a relese? I have been rifle hunting for years and now need a new challange. Thanks in advance
