I found a 156ish Blizzard Boss a few weeks ago and I've had it in my bag for max D. I have some form issues that are keeping me from really getting the most from this disc. I can get it near 375' on a good throw (RHBH), but it tends to be much more errant than my other discs (which I know is in part because of the faster speed), and I can sometimes match it's distance within 0' to 20' with other discs (Valk and Sword for instance).
So while I know I have form issues to work on, I wanted to see if there is a general rule of thumb that you guys use with these discs. For instance, how far would you say a player should throw them before they are of much advantage (relative to other discs)? I realize this is entirely subjective on the thrower, the disc, etc, but give me your thoughts.
