RE: What is better???
First off let me tell you I am not a bowhunter for turkeys (as of yet!)
But I can tell you to bring a bow at full draw without a blind is a higher challenge than in a blind!
This is based from my experience using blinds - whether a simple open rag panel type blind or fully enclosed! The Rag - a Flat pannel in front of you, is a bit more challenging than a fully enclosed.
Why??? - Movement - movement at the wrong time seen by that turkey and they are FLAT out gone!
A turkeys vision is such they can see 240 degrees around them. I swear at times they can see right through a big ole tree trunk as I tried to move the gun just a bit!
