photoread4me,
BOTH work best when you have an idea of what you want.
BOTH can work at a fast speed with no real concious thought.
BOTH can bring back related points of interest, etc...
BOTH could be pretty much devoid of conscious effort.
Like brain, I hoped that that first item would not be as important with PR.

From a possible scientific point of view I wonder if the principle as in so out applies, especially as to the last point; 'BOTH could be pretty much devoid of conscious effort'
What I mean the less conscious effort in and so too you must match it by consciously accepting a mere whisper to get it coming out.
Another more direct explanation; the more 'effort to activate' is matched by more effort or matched intensity by the supra-conscious to give it back.
