Hey Robinhood1389,
I have been researching different trad turkey setups on these forums and I have found a lot of good threads. I did a couple searches for "turkey broadheads" and got lots of good results. There is a whole list of broadheads and everybody explaining why they think one is better than the other.
A lot of people recommend the big 160 gr 3 blade Snuffers which seem to have about one of the widest cutting diameters of any equivalent cut on contact head.
It seems that not too many trad guys use the REALLy wide BHs like the Guillotine and the Bullheads or whatever.
here is a good thread on the subject:

But there are still people who think the arrow being stuck in the bird can immobilize them more. It seems to be an ongoing debate, but it sounds like it is hard to get total pass thru anyway..
Here is another good thread:
http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=042292#000000 Guru talks a lot about Trad setups for turkey and has posted a lot of good info about shot placement, vitals locations, BH selection, string trackers etc.
Good luck with them turkeys!
