I'm not a "big buck" hunter, there are just not many local opportrunities here to hunt particular whitetails and I dont have the time needed if they were. If I were hunting some huge buck, I'd pay close attention to every little detail and definitely pee in a bottle. I'd rather not chance it.
For my normal hunting, I'm not going to be heart broken if a "normal" deer spooks. If I dont feel like hefting around a bottle, I'll go. If I feel like being super sneaky on a particular day, I'll bring the bottle.
I'd rather go far from my hunting areas though, I like to think leaving as little clues to my being there as possible is best.
