Hi everyone, I was wondering about shooting 22 inch arrows through the carbon express sls. the company offers 20 and 22 inchers but what is the difference? Would 20 inch be for target practice and the 22 inch for hunting? It looks like most here are shooting the 22 inch arrows if I am not correct? Of course the xbow I bought came with the 20 inch arrows. Should I go with 22 or not?
