After briefly trying a tripod, I find them no more stable in a sitting position than sticks or a long bipod.
And they’re a lot of more of a pain in the ass from a maneuverability/packability/weight standpoint.
I used a 9-13 Harris for years and just packed sticks for those sitting situations. Mostly in the summer.
As we used to say, “get your dick in the dirt” if you really need to shoot.
I tried a gen 1 Tricer and was sold on it. Besides the stupid pan feature, it checks all the boxes. Ability to get low prone all the way to sitting with one maneuverable, packable, light weight unobtrusive device.
