yes i know there r some advantages of butane but have never used it on long treks so cant really comment on it. but my point is how much will u carry for whole trek????
and ul have to carry extra incase of contingency???
Rahatlatif knows very wel what happened with the trekkerz group at ali camp. so in case of emergency what will u do if u dont get butane there????
ul have to consider all these aspects b4 deciding.
