Shoot, if the Redbone were, in fact, more realistic than the competition, even I would use one. My little prejudice isn't so strong I'd short myself in the field over it. But I was as unsold by their taped comparisons as what I've heard in person. Edit enough speck recordings, and you can probably match your picks with most speck call makes. Yet no one call I'm aware of comes close to matching the spectrum of tones you'll hear from the real deal.
If you think I'm wrong, you might be right.
