Hmm very interesting, thank you for the reccomendations . What do you mean by "actually overstable" discs that would be too beefy for throwers of my distance?
There are VERY OS midrange discs vs ones which are stable to OS and much more workable (straight with a little fade at the end)
check out this: http://www.dgcoursereview.com/forums/showthread.php?t=13546 for more background on OS vs stable mids and how they work for peoples games. Persoanlly I would stay away from anything "Very" overstable or "actually" as the other person said.
If your issue is that the discs are not fading enough well then I wouldn't worry at all which mold you are throwing but leanring how to make them fly the line you want. Any midrange can be manipulated to fly different lines due to its slower speed.
