The ti hook stakes are still on sale. At these prices they are cheaper then Vargo stakes at wholesale. Its like a mini TheClymb deal haha. Especially when you consider you only need to order 7 of them to get free shipping : )
As far as the Hex vs. Round goes, I have built and sold ALOT of round ones since I started making and selling these. The hex rod was a special one time deal I came across and at this time, I can't get more. That said, I find the round stakes work exactly the same. I think the only difference is the hex ones look cooler.. But I promise you the ground doesn't care. haha..
Thanks for all the business,
