Used to have several different UL Esbit stoves, all constructed of Ti- very light for sure, but quite frankly a pain in the ass most of the time. Esbit w/ a little wind can be a pain to light, boil times are higher, your pot gets coated with a dried on (very sticky) film.
I've gone back to canister stove, even with the fuel canister it's only a few ounces heavier than an Esbit setup. The convenience of the canister stove far outweighs the weight savings of Esbit. Had a buddy this year on the Bob Marshall Open who brought his Esbit setup, in the morning I was just about done drinking my coffee and his Esbit was just starting to boil the water
