Stakes are the often the first thing folk like to grumble about but really there is no perfect for every terrain solution.
(see reviews at BackPackGearTests for that)
If nothing else with TT they are included in the price.
As much as many like the Y types, others don't because they either cut themselves pulling them out or step on them or get annoyed because the collect dirt.
And that is why there are so many types available.
I always have two or three types of stakes with me and often do use rocks/branches /sand bags to help the stake to hold.
Personally I like the 8" Easton but also use Ti nail stakes, Y stakes and thin Ti shepherds hook type and snow stakes in winter...
