I drew a sheep tag and need some recommendations on arrows. I currently shoot Gold Tip Velocity XT but feel they might be too light for sheep as they only weigh in at 350 grains. I really like Gold Tip arrows but am open to suggestions. What recommendations do people have as far over all weight of the arrow, broad head weight, 3 or 4 vane fletch (if this matters)…??? My hunt is not until the last two weeks of October but I want to make this decision so I can start shooting these arrows. I shoot a Heli-m 28” draw at 70# if this makes a difference. Thanks for the help.
