There is a useful thread currently under the Turkey Hunting section of the forum. Good luck. I've tried for the last couple spring seasons with only my bow and haven't been able to succeed yet. It's a lot of fun.
Here's a read on gobbler broadheads http://www.bowhunting.com/blog/2014/4/2/top-10-turkey-broadheads/
Any broadhead you use for deer, bear and elk should be fine for turkey. Biggest key to being successful with the bow is shot placement and ability to hit very small targets in the field. Taking a turkey with a broadside shot is difficult. So is hitting the neck/head unless you have a large cutting diameter. Best shot with the bow is directly toward hunter or directly away from hunter. Center back going away is absolutely the cream of the bow shot crop! This brings up the importance of having a bow you shoot extremely accurate. Most of my turkey hunting is done using a bow I purchased to shoot 3-D tournaments. I use a long stabilizer and a single pin sight. I just can not get too accurate when hunting those darn birds. You also want to have a bow you can shoot super accurate from your knees. I've only taken a few shots at turkey while standing up. Most of those were follow up shots after trying to take a bird with a broadside shot. Similarly I chose my turkey arrows based upon how accurate I shoot them. I really only need power if I miss my target. And I only need durability if I miss the whole dang bird! I also do not need super flat trajectory as most shots are inside 25 yards. I would say any bow/arrow/broadhead combination that you have confidence hitting a golf ball sized target will do. That should also be your measure of shot distance as well.I have only taken two turkey with a gun so my knowledge base there is limited. But I can tell you that tagging that first one with the bow is crazy exciting! To me there is just no comparison in thrill and personal fulfillment between shooting one with the bow and shooting one with the shotgun. Every bowhunter should attempt to tag a turkey with their bow at least once!!
