while I think double bow has points - I am doing the traverse next weekend - while I have never done one before - but I have done half traverses (valley-way and down tucks), etc.. I am going light - light doesn't mean don't pack a jacket and shells and head off in flip-flops. - it means don't bother with tent, sleeping bag, extras of everything under the sun.
I think if you know the area, have done a few of these peaks before, know the escape routes, are a decnet paced hiker etc.. this can be done fast and light - very easily. In summer - you have a few places to hit if the poop hits the fan and you can get to them quick if need be. Madison Hut, RMC cabins, Lakes, Washington summit, Mizpah. .
sherpa john trip this past weekend is a perfect exmaple - he knows the area, is a strng hiker - and did this light and fast very succesfully.
