Why use RCD's?

I don't utilize a RCD but I can definately think of some circumstances where they would come in handy. And if you pair a RCD with the right pack of dogs they could be very effective and help each other from getting too torn up. It seems that a a good pack of rough short range hot nosed curs paired with a good RCD or two would catch a lot of hogs in the right terrain. Long range dogs with a RCD would be bad and a RCD on a property that is heavy with the thick stuff would be bad too.

I thought about using my catdo as RCD during grain season because of how good his lungs are and how fast he is. I did it one time and it worked great. I noticed all of the curs get gone and about 300 yards from us I heard him get there and the fight was on. A quick 300 yd sprint thru the milo and it was all over in less than minute. The second time was a disaster. I unclipped him, he ran 1500 yds (a good ways further than most of my curs hunt) with his nose down on to someone elses property. I sat at the property line trying to call him out and he finally comes to me 30 minutes later with a blood all over his mouth and muzzle. I'm 99.9% sure he probably found a coon or something like that to crunch on but I quickly realized he won't make a RCD because he has too much drive and is hunting for himself not bringing muscle and holding power to the pack of curs. Now if I had a couple more just like him....
