When do you release your CD?

From what I'm reading here it sounds like I release mine from farther away than most. I like for the catch dogs to be athletic enough to run and strong enough catch and hold until I get there. So, at the first good bark I'll often let my first dog go (he's more like an RCD), or if its already a solid bay I let them both go (usually have 2 catch dogs - one more like an RCD and the second more typical lead-in catch dog). I think I get more stopped/caught that way then trying to walk in real close and running the risk of pushing them or breaking the bay. Of course it depends on the situation too - the place I'm hunting, which dogs are on it etc. If I'm hunting with dogs I don't know/trust as much of course I will hold the catch dogs back longer.
