I don't know if accuracy is the term I'd use. Overstable discs can be extremely accurate you just have to count on the fade and factor that into your throw. Understable discs will naturally fade less but sometimes seem less accurate because of a tendancey to turn. I play 90+% of all my non-putting shots FH. I am gradually moving away from the fallacy that the best FH discs are always overstable. The best FH discs are the ones that you can throw with less effort while shaping the lines you want. I am finding that my most consistent discs are ones that started out stable to overstable and have since been beaten into submission (Wraith, Destroyer, Surge, Crush, Tracker, TL, Shockwave, Buzzz). As you well know, form is always the key. Any disc that can be thrown BH can be thrown FH providing the form is clean.
