I use a double bull chair, the reason being, it doesn't cut off circulation, I can transfer to one knee or both for a shot. It is lightweight 2 1/2 Lb. They are $29, and if you break them, double bull will give you another one no charge.
I use a double bull blind, and have had no trouble to as long as is brushed in., ground blinds are just like traditional hunting, if you have an attitude that they don't work, they're not going to work, but if you take the effort to make your blind, rather its homemade, or purchased, it will work, some purchased ones better than others, the double bull, will work a lot better than the nylon ones. I hunt on the double bull all the time. No problems as long as they do the work. The best thing is to break up your lines, and wear black, including a face mask. And especially on hand its holding the bow, closest to the deer. My double bull ground blind weighs in at 12 lbs., I have the light rides in it, it keeps the warmer than those other cheaper lines. That means I can hunt longer, wait out the deer longer, get my point.
I to was one of those guys that said they'd never owned a $400 hunting tent, is proved me wrong, but it's been very enjoyable.
