I have been to enough hunt test to see and hear the whining about a long blind all the time. Yes they do whine. I hear it...The rule are 125yds that's too long" Never, ever heard a whine from the field trial folks, ever. I also heard if training with hunt test guys. I'll put a blind 300 yds out and the whining starts, "this isn't a field trial why's the blind out there?"
