I'm starting to get tired of the "more distance with less effort" claims on all these speed 10+ discs just because they're understable. Unless I'm way off my mark, the core principle of max distance on any given disc relies on getting a disc up to speed. If you want more distance with less effort, throw speed 7 or 8.
Of course, it's also possible the "reality" of what a speed 10 disc is today is much different than what a speed 10 disc was even a few years ago (since "speed rating" is mostly an arbitrary assignment anyways).
