Lots of good points here. If anything to add:
1. Camo not critical at all. I've killed em in earth tones at 6 yards. The biggest thing that will bust you is -- lots of guys have said it -- movement. If and when you do move (get gun up for example) you are going to do that when his head is behind some sapling or if in the open when he gobbles since his head is shaking violently and he won't be able to see you with great acuity.
2. Rather than rely on camo, always strive to create really good setups. That might mean setting up in a ditch, around an impenetrable cover of brush, just beyond a short rise. I know this is not possible ALWAYS, but can't tell you how many turkeys I've killed by luring them around some obstacle until WHOOOM they don't even have a chance to see whether I'm wearing bottomland or kuiu or whatever.
3. All that said, lightweight ghillie shirts and hats are awesome. I wear the First Lite top and mask just because that's what I got a good deal on a few years ago, so I and wear these religiously for turkey season. They move with the wind. Super ninja.
Not ragging on any camo type at all. Most important thing is be comfortable and don't let those turkeys know you are in their house until it's too late.
Good luck this season everyone.
