Just ordered some titanium ones from here: http://lawsonequipment.com/All-Produ...akes-p883.html
Cheaper, lighter, and stronger than MSR Ground Hogs
I believe they're identical to the GoLite stakes mentioned earlier, they work very well. I also have some Groundhog-style stakes but don't use them as often.
These topics are a great learning experience.
Since reading this thread, for instance, I've ordered groundhog-type stakes from DIY Gear Supply, dug out an aluminum gutter spike, and requisitioned a couple of knitting needles, intending to follow what is true and confirmed above that we tend to encounter a variety of circumstances so need different kinds of stakes.
I've given away all my plastic and steel stakes and hope to afford some Ti ones some day. Until then aluminum will have to suit me.
I've always carried, though, in additon to stakes, plenty of cordage to tie off to trees, bushes, picnic tables, rocks, et al. It can get ridiculous sometimes, huh?
Tied off to a sitck in the ground before but never did anything more than break it off for a pointed end. Edges on knives and hatchets, perhaps, mean too much to me?
