New for this season if money is no object is the Petzl Nao with adaptive brightness. It gets good reviews so far. I agree the Petzl Tikka is good though I sometimes fumble for the flip-down diffusor. The LED Lenser H7 is good, with a power slider on the back of the head. Princeton Tec is good with both lesser diode diffuse light and one central more lowerful light. Most of last season I ran with a LED Lenser T5 handtorch as well as, or alone, held at waist height to throw shadows better, e.g., roots, rock. It's also useful to have in the hand on pavement in town to flick on athazards e.g. road junctions to warn cars, even if the streetlighting is otherwise adequate. If you carry both a head and hand torch you're never caught out, practically speaking.
