I like the call and the stain idea. That barrel looks an awful lot like Crawdad's though, and bears a similar name.
Edit: Wrong choice of words on my part. I was trying to point out this similarity but it could have been errantly perceived as an attack, which it was not intended as. I put something on the forum that I should have said by private message and CLRiggs (who has been very gracious) has my private and public apologies for pointing this out on the forum. In the future I would do the same, but would opt to do so in a more delicate manner and would do so in private.
