I have no experience with full blooded Ridgebacks... but my experience with hog hunters tells me he is stretching the truth to make a sale or has not been hunting long. If you hunt long enough you will come across a hog(s) you can't catch. He may have good dogs, but they are no super dogs. If they were that great, we would ALL be using them already. He isn't inventing any thing new over there.
Get your snake boots, long sleeve, gloves and tweesers together and go hunt with him before you buy any thing. I have hunted in Three Rivers on property that borders Choke Canyon (big lake). That would seem pretty tough to bay and shoot around there.

In my opinion i think its the dogs brain that makes it able to hold a hog than its size there is some things that you can do a certain way and not have to use much force. Kinda like work smarter not harder!

That's not opinion... thats physics. You are exactly right.
