I really like the convenience of a canister stove, I have the Optimus stove and pot that has the heat exchanger on it. As I am a gram counter I am looking to shave weight, but I really like the boil time of this setup. Any thoughts on getting a different pot (ti) that does not have a heat exchanger and do you think it would slow my boil time down/take more fuel? Love to hear experiences and preference.
