Here's what I would do in your situation (cooking for five): have each member of your party pack one fuel cartridge for every four nights you plan to be on the trail. This should give you plenty of fuel for preparing two meals a day (breakfast and dinner). I assume both stove models use the same type of fuel cartridge.Thinking of having two stoves to speed overall preparation time: one Pocket Rocket and one Brunton Raptor (11,000 BTU)
Oatmeal +coffee/hot chocolate at breakfeast for five.
Breezer Bag Cooking recipies at supper +coffee/hot chocolate for five.
Thanks
One trick I use is to label (with a Sharpie pen) each cartridge so I can tell them apart. I like to completely use up one cartridge before using another. I always end up with extra fuel.
About bears: the best way to advertise that there are humans around is to light a campfire. It is a bear siren song, a far more effective lure than toothpaste spittle. Don't worry too much about your toothpaste spit. I like to brush my teeth a little ways from my bedpad, near the creek or lake. Bears are smart. If they happen to notice a little toothpaste spittle, they will have noticed other human smells well before that. They know you're there. They're not interested in a little toothpaste spit. It's your food stash they're after and they are smart enough to know the difference. Store your food wisely and you will have a good night's sleep.
Have a great hike!
