My problem with Lunas is that they cost just as much as all the other bars but weigh in 60 calories light.(carm apple vs powerbar chocolate) I feel cheated when 1/4 of my calories are missing.
Besides powerbar has come out with quite a few new flavors(even s'mores)
I like to stick 4 different powerbars flavors together to make what I have dubbed a "Superbar" with only 900 calories.
I discovered the Superbar during an adventure race, I didn't want to futz with packing out old sticky wrappers and tracking the location of multiple bars(on top of 45 pieces of mandatory kit) so I unwrapped several bars pre race and put them in one sandwich bag and, after a spell, it was born.
I think I had calculated 10-15 thousand calories for that race.(Nonstop clock as all true Adv. races are. Even ten day races
)
