My Open Cirrus had a drogue chute in the tail. I used it once just to practice using it, and then it saved me from a broken glider on a very very short field landing when I had to use it for real. Don't try to deploy one unless you are over your landing spot, it's damn near a straight down ride once you deploy it. You really have to push the nose down too maintain airspeed with it deployed, but the landing isn't difficult to do, its just an unusual attitude.
