I have four tents used for all types of camping (from car, backpacking, winter use) and over the years have replaced the pegs on all with Groundhogs. The MSR offerings are incredibly strong, less prone to bending than titanium and lighter. I've never actually bent one. Which is something I couldn't say to most tent manufacturer's standard equipment. The Mini Groundhogs are handy for backpacking and the full size versions best for winter use.
I've used these stakes with my Alpkit Rig 7 tarp. They have performed flawlessly in wet and hard ground areas. I am going to buy another set now, excellent hardware.
