I had a m100u, great stand but not what I consider a lightweight setup if you walk far or climb steep hills.
I wanted to try the M60U, I think it weighs about 12 or 13 lbs. a little more compact.

Or the m-7 microlite

I switched to a saddle this season from a climber.
Cut down to around 16 pounds
It was OK for bow hunting but a lot of movement unless the deer is in the perfect spot.
I spent a lot more time trying to find a tree that had cover within my 20' of climbing sticks. (climb any tree... maybe but you gonna stick out like a transformer on a telephone pole in alabama)
Took a lot longer to get set up
Absolutely sucks with a rifle.
After first hunt with a rifle I went back to climber.
I will use the saddle some next year but also bought a lone wolf assault.

Dead Ringer tree-hammock seat for ground hunting, especially high on ridges. Packs into small bag, weighs 1.2lb. That my pack, gun, ozone generator, and trigger stick all together in at under 17lbs. Other than that I'm going up in one of my Vipers. I tried an X-Stand and Lone Wolf Sit N Climb, bc of their weight, and I'll often walk in 3-4 miles on public land, but at 260lbs they didn't sit well enough to warrant the change at only a 3-4lb difference.

M7 microlite and 4 beast sticks, here. Pretty comfy for the weight, packs good, and relatively quite.
