are overstable discs really the best for these shots?
for distance I use overstable discs, but for (what I call) pancakes, I use understable plastic. Understable when thrown vertical will flip and land top down and slide, this can be very useful midrange when you don't want a roll or fade.
as for best thumbers/tomahawks for me
Epic (thumber distance)
Illusion (thumber/tomahawk and can also do a good pancake)
Teerex (thumber)
Banshee (shorter range Illusion, but the pancake has to be more forced (released more at 100 degree angle, 0 being sidearm))
Flick (thumber)
XL (thumber)
edit: right now I use a sidewinder for a pancake
