Really... If you can take a stance by only moving a reasonable amount debris (if desired), then YOU need to make the right decision on the TYPE of throw that will result in NO injury.

Just because you aren't presented with a perfect stance area doesn't mean that you can move to your lie to your liking. There are plenty of different throws available to get your disc towards the target.

Yes, the "spirit of the game" should take priority. Play it as it lies.

IMHO, the only time you should get relief from a debris pile is when the pile is very large and you can't get at least one supporting point (foot) contacting solid ground for safety's sake. Pretty much the same throwing option as being in a large bushy plant/tree.
