Shot my shiras 4 years ago, I was using 100gr shuttle T's on 300 acc pro hunters. I had an alpha max set at 78 lbs. You don't need a lot of draw weight though. The next year a co-worker got his wife in on a moose and she folded him up pulling 45 lbs. My personal preference is a strong, sharp, durable broadhead and an arrow that's a minimum of 410gr. My arrow on that moose was 442gr. Like ivorytip said, whatever you use for elk will work. You don't have to have a setup to kill a tank. Just make sure its durable and your confident that it will hit where you need it to. I know shoot 70lbs with injections and an exodus broadhead and I think it performs better than the setup I had for moose. Id be glad to answer any other questions you have....good luck on getting a tag, its addicting.
