I'm looking at some soft luggage that would be used on my '07 EXC450 and SXC625. I don't have a rack on either and want to get the weight out of the camelbak. I think the Wolfman Day Tripper would work fine, (a 21" tube, irons, small air comp, some tools, some misc), but see the E-12 is 2x the size in terms of width, about 6.5" instead of 3.5". I suspect I wouldn't need the 6.5" often and could cinch the width in but having the 6.5" available when needed might be a good idea. I may want to carry a fuel bladder/bottle in one side when on the 625. Also how about the Giant Loop Mojavi? Anyone used these and have some recommendations? Thanks all.
