Wow everybody, thank you so much for all the advice. I really came to the right place! I guess I've totally been schooled and I'm really glad I was.

TomD and OregonMouse, you are of course right that I am using isobutane, not sure how I messed that one up. And to everyone, I'm not sure how I arrived at that 40 min estimation other than I figured ~15 to boil water for oatmeal/coffee breakfast and ~15 for dinner/cocoa and rounded up. This was, not smartly, a blind guess. You're absolutely right that I should test out my stove and fuel and see how long it takes and the weight difference in fuel. I admit that although I've been backpacking for multiple 4-8 day long trips I was never "in charge" of the stove/fuel/kitchen gear so I (stupidly) did not pay attention.

I won't reply to everything but know that I have read your comments thoroughly and I'm taking it all in. All the help you have all given me is invaluable and I really truly appreciate it. Happy backpacking
