Jetboil Ti 9.9 oz + empty canister 3.3 oz = 13.2 oz
The three setups below;
SP 900, GW, windscreen, lid, empty bottle = 6.2 oz
SP bowl, Ti esbit wing, windscreen, lid = 3.1 oz
Heiny, lid, GW, windscreen, empty bottle 3.6 oz
Savings of 7 to 10.1 oz carry out weight, is that significant enough?
Plus you can use alcohol to start a camp fire. My personal preference is to just bring the SP 900 and use rocks to make a stand and fire under.
