In reply to ModerateMatt:
No one really minds, it is only a bone of contention when you competitively compare your performance to someone elses, or they compare theirs to you. This tends to happen when you are climbing with friends (or people you know who aren't friends, but you measure yourself against,) or you are pushing the boundaries of the sport.
And yes you may log Cave Direct as it is a variation, and congratulations. Just be careful to admit to having climbed Cave Route in the past, if anyone questions the ascent.
