I prefer less back end too. In fact, I prefer a straight stake. I find the big back end a twisting pain in the neck. It allows small amounts of lateral sideways movement in a guy line to apply twisting forces to a stake. A straight stake can't do that. Twisting forces on the stake shaft help loosen the soil holding it in, which in turn leads to pulled stakes.
I bought up a bunch of the old 1gram BPL Ti stakes, but found them useless due to the big bend in most soil. If they were just a straight bit of Titanium rod they would have been much better.
Also, try pushing a shepherd's hook stake into hard ground, or giving it some persuasion with a rock. You guys must hike in pretty cushy ground.
