I've used this style fly a lot for silvers and humpies. Works well in deep pools when the fish are stacked and seem to be non biters. I think the rising and dropping action of the weighted fly is what stimulates this. I usually use marabou instead of bunny fur for more movement in slow water and don't use jig hooks, though tie the eyes so the fly works point up in the same way. And yes you could snag fish this way if you wanted to, but I'm fishing above the fish and have seen 5 or more fish peel out of the school to chase the fly. Pretty cool.
