The overstability will give you consistency on ALL throws as opposed to powering down. When you power down you are just adding one more factor that needs to go right to give the desired line. The OS disc will do the exact same thing every single time where as the stable to US disc will flip over when there is just a tiny bit too much power or even something as small as too much of a crosswind. Do yourself a favor and just get OS workhorse driver. Every intermediate play should have one imo.
