I have most of the high speed drivers. Halo, Nuke, Lace, Rampage, destroyer, Cannon, King, Wraith, Boss, Ape, Nuke OS, Blizzard Boss/Katana/destroyer, Krait, Force, and probably a few others I've forgotten about. The Halo (Opto 172) seems to be the most consistently long disc for me at around 420' or so with a normal line drive. I've flexed out Destroyers and Rampages considerably longer than that, but the Halo seems the easiest and most dependable on the course. Nuke is my bench player, and the Rampage takes over if there's wind.
