I shoot a Bear Cruzer g2 at 50lb draw with a 24” draw length. What spine arrows should I be using and what would be some recommended broad-heads for both whitetail and turkey to ensure I am ethical in my hunting?

With a 24" draw length I'm going to assume your arrow is roughly 24" long and you're shooting a 100 grain point. At this specs, most arrow manufacturers are going to recommend a 600 or 700 spine arrow. I would use a small, sharp, fixed-blade head for deer and an expandable for turkeys. I like the NAP Endgame or Thunderhead Nitro for the fixed-blade and a Spitfire 3-blade for turkeys. Good luck out there!
