Not a fan of sitting on the ground/rocks/etc even with a pad. The ground will sap your heat away in short order. Makes it easier for insects and arachnids to get onto your skin; I know the WKR moniker is far more effective at keeping ticks away than permethrin. While have acupuncture performed on your testicles and/or anus may "float your boat", it is not something that I personally enjoy.
I'm not a fan of standing from dawn to dusk either. Harder to get in the shade when it is hot. If it is windy, it sucks even more. Not a fan of letting the world know where I am.
Like most things, use the right tool. Sometimes you don't have much of a choice and have to sit on the ground which lends itself to using a pad. Sometimes the terrain is pretty flat and stable which allows the use of a chair. And other times a stool works best as it can handle a variety of terrains and angles.
I find it hard that the manly men of RS, that wield 12+ pound rifles and can throw an entire elk over their shoulder, find the weights below too bone-crushing to handle:
* Kuiu glassing pad: 1.9 ounces
* BTR stool: 14.3 ounces
* Helinox One chair: 12.8 ounces
What's that phrase that folks say when you don't want to carry a heavy rifle? Oh yeah, work out more.
