When I say "ceiling," I'm talking about stuff that's above the fairway that a disc could hit, mainly tree branches.
I find that putters and most midrange discs need a good amount of height to get the best distance out of them. I'm bad at estimating distances, but I'd guess that when I throw a putter as far as I can in the open I throw it 15'-20' off the ground. If it goes much lower than that it will hit the ground before it fades at all, which means it could have gone farther if it were higher in the air. If I throw a midrange at a similar height, I'll get a bit more distance out of it and a harder fade. I can throw a midranage lower, say 5'-10' high and get less distance, but I find that harder to excecute while still being accurate. They tend to lift up on their own more than putters do for me.
The tweener discs are similar to the midrange discs, but I find they are easier to throw lower and tend to lift up more than midrange discs. Many of the discs in this category that I've tried to throw high end up stalling out early. I can either try to keep them low and get the same distance as a midrange thrown high, or throw them normally and they'll go 10'-15' high and get their normal distance.
The drivers I throw I have to throw 5'-10' off the ground or they will stall out and not get good distance. Because a small variation in height will cause a fairly large variation in distance, I try not to use these discs when I want to limit how far I throw. I'd rather come up 50' short with a slower disc than risk landing 20' in a pond rather than 10' short of it. If I have a shot where I want to go at least 330' and have some room side to side for error, then I know it's a good driver shot.
