I've thrown a few star Bosses that flew like champion Terns out of the Box. I think you can already minimize that way if you just look for lower/higher PLH Bosses (or Champ/Star/GStar Terns although it's harder to find a more OS champ Tern I think).
I guess maybe the bit about people not being able to handle high speed drivers refers to people who can't get them up to speed, but if you want a more understable high speed driver than the Boss, you can already get a Katana or Vulcan. Also, I think most people on here would agree that if you can't get high speed drivers up to speed, you're better off in terms of reliability discing down to a lower speed driver you can actually handle than trying to go for a less stable high speed driver. Discs like the Katana and Vulcan when I used them in the past were always really touchy, which is why I don't use those anymore. Sometimes they would absolutely bomb, but it was hard to get them to fly consistently. The Tern seems a little better in that regard so maybe this will be the speed 13 (14?) version of the Tern.
