I've spent 22 days in the outback of Australia last Nov 01. My opinion is if u r going to do that much hiking, get a proper walking stick cum monopod. Singapore has quite limited selection. Campus Corner at Capital Building is selling the LEKI one. You may want to check it out. Or check out CP for a cheaper and lighter SLIK one.
If you choose to buy them overseas, there is more selection with brand's like LEKI, Maluku, Petzl, Black Diamond etc. They are all in the range of S$80 to S$110 each. If budget a,llow get the type with spring loading ones. Compare with the heavier and dearer Manfrotto or Gitzo ones, these walking stick work better and more convenient.
So, u can imagine my torment 22 days in the outback carrying the Gitzo G1556.
