Thanks for the Replys guys...

I designed these calls with a few things in Mind....

1.Loadability....Meaning the call has the internal demensions to hold or store air, so that every note doesnt have to made from the lungs....
2.Volume, yet the ability to get soft when them dogs are trying to figure out which way to turn...
3.Control.... a call has to have control... If it tops out and squeals, thats not to realistic...

Like I said I appreciate all the comments..

Thanks
MIke
