When throwing MTAs the goal is to throw up into a crosswind on a hyzer and get the disc to flip and then glide long and slow with the disc beginning to helix (S-curve) and get a flatter and flatter flight pattern.
Most non-overall players that ended up in an overall competition tend to throw the disc directly into the wind and hope to make a clean catch. When you're trying to maximize the amount of time the disc is in the air, you want it want it to have a gentle helix while coming down as flat as possible.
If the disc is coming down flat you can milk the flight all the way to just inches above the ground.
FB3s are great discs but very hard to find. FB 12s and higher numbers can get you numbers into the :10 and :12 second ranges of throws but to hit anything close to :14 to :16 seconds is most likely to be a FB3.
World record was, however, thrown with an FB3 and it was 16.72 seconds. I believe it was thrown in 1984. My personal best is over :14 seconds with a clean catch. I had a couple of throws over :15 seconds that I was able to hang on to the disc. In all those cases I was laying out to get to the disc.
