Some discs that come to mind
Predator: Love it, but I have T3's and Firebirds already in the bag and I feel it falls into that spectrum of stability.
Wizard: I will always have a stack of these around the house, currently using Judges but I can go back and forth between the two. I practice putt with them still, but bag judges.
PD: I like having them in the bag, but I end up reaching for my Tee3 most of the time, I also have a Koling Thunderbird for that PD spot. Maybe I just have a stable workhorse driver problem?
Patriot: Leo3 and FD seem to take care of all those duties. Still love the disc, though.
Meteor: I always want to have one, but I never find myself throwing the shot. I usually opt to forehand or throw a putter anny instead.
Harp: Hasn't quite been able to replace the Zone. Still bag it sometimes for funsies, but I reach for the zone come tourney time.
