I make small weight "sins" when deciding on items I purchase. For example, I do have a Vargo Jet-Ti canister-top stove but I just bought a 0.7 oz. heavier Brunton Flex burner.
Why? Because it has a larger flame ring for more even heating and larger pot stands B/C I use a JetBoil 1.5 L. pot for all my cooking. (Efficiency & fuel savings on long trips) The wider pot suppports make for a much more stable cooking setup.
So there is yet another small "sin", the JetBoil 1.5 L. pot - minus its steel wire handles. I use a very light aluminum pot gripper.
Also, in the kitchen, I use a plastic folding 3-legged gas canister support, again for stability. Ever dumped your entire meal because your stove was wobbly? Hmmmm? Betchya have.
OK, so I like to cook and I "live to eat", not the other way around. A few ounces extra in the kitchen equals faster and better meals.
I do freezer bag PREPARATION of ingrediants but don't like the idea of plasticizers in my food so I cook it in my pot.
Other little "sins"? Carrying MSR Groundhog "Y" cross-sectioned aluminum stakes for far better holding power than the ti stakes that came with my Contrail tent. A teensy bit more weight with no aggravation from popped stakes in loose or rain-soaked ground at 0 Dark Thirty at night. Plus these suckers take a beating when pounded with a rock.
Another "sin" is a Garmin Colorado GPS on some trips where I've never been before. Plus two spare AA lithium batteries.
Finally, my Danner 453 boots. Not running shows by any stretch, but they are SO comfortable on a week long trip. And, having Gore-Tex, they keep my feet dry when it rains all day.
So, yeah, I have a few weight "sins", for which I do my mild repentance with every mile. But "at the end of the day" as the overused saying goes, I like my little venal weight sins more than the discomfort of not having them. Are they much more weight than the left over Cliff bars you have at the end of a trip? likely not.
What are your "Little Weight Sins"? You can confess to Father Eric. 'Twill do ye a lot of good to unburden yer soul, my Son/Daughter. And don't forget to be sending along a wee bit of absolution money to me to be extra sure your sins are forgiven. Now then, do as yer told.
