The beauty of the Spartan bipod system is how quick it is to deploy and take off. Or leave it on when stalking in, etc. It takes around 3 seconds or less to deploy or remove. I keep a short bipod in my bino harness or pocket and the long bipod down the back of my shirt or jacket, strapped to pack, left on gun, etc.
Timed seated shots with trekking poles are the only thing that’s almost as quick as a Spartan bipod. Still not as fast and guys fuss more with finding the right “height” instead of already having the bipod height set correctly and moving their body to build the position and get a shot off quickly. I also find it more stable to have my offhand in the same position as my standard prone position, versus trying to pinch the gun in the “V” of trekking poles with my off hand. Try both and shoot for 10-20 shot groups and see what works.
Adding a pack for rear support in this position is nearly as stable as prone for me. With no rear rest but having something to rest my back against, it is also very stable. Back to back with a hunting partner works great, a tree or rock or vehicles tire etc. is even better. I am repeatable seated with no rear rest as below, out to around 600 yards on a 10-12” target.
Tripods downfall is they are by far the slowest. Tripods are viable if you have ample time to setup or are ambushing an animal you’ve glassed up. Otherwise they are pretty much useless for shooting quickly.
Fixed bipods suck because they get in the way of off pack and prone shots and make offhand shots more off balanced. I also just hate carrying a gun with some clunky bipod hanging off the fore end.
