Ok I consider my self an expert on this matter. I have thrown pretty much every supposed great thumber disc out there from a X Reaper to an Epic. Here is what I know, for the most distance use an overstable disc like a Monster or Predator. But if you want a disc that will fade more at the end (turn right) then use an understable disc. Personally I like a combination of both and for that the SL is the best thumber disc I have ever thrown. It goes a mile and has a very predictable fade at the end, basically point it 35 degrees to left of where you want it to go and it goes there period. For shorter shots (170-200) the best disc is the Discraft Elite Z XS, it is my go to disc for any problem shots and for shorter drives its fantastic. Finally if your just learning and don't want to throw down on some expensive plastic I've found that DX Eagles work really well.
