Maybe I'm strange but I find it easier to throw stable to slightly overstable discs on low tunnels.
150-250 FLX Buzzz. 250-350 Opto Strikers. I like to throw my understable discs in the air and let them ride the glide they posses. Not saying that I can't throw them on low ceiling shots, I just prefer not to.
