I agree w/RdFx . Why drive two stakes when you can drive one ? I have had spots where I wouldnt be able to drive one stake let alone two due to soil conditions . In theses areas , a disposable was only 12" down and was way more than needed . I also look at the weight issue . I can also carry a dozen disposables in my pocket if need be , they dont take up the room rerod does . I usually attach #11 wire to mine ahead of time but also carry extra wire in my pack just in case I find a really soft area where the stake needs to go deeper .
