I used varied, immprovised field shooting positions for many years, in all terrain types and did not have much of an issues, except when there wasn't a handy tree or bush big enough to get above the buck brush or willows.
I have a Bog Pod tripod that I have used intermittently in the field over the years, but have preferred using the Trigger Sticks since getting them as they are quicker to deploy when in the field. I have the single stick, but did get the tripod version for my wife and daughter for its added stability. If using as a walking stick, I do not put too much weight on the single, and if using the tripod one, I bind the legs for this purpose with its strap for the added strength. Haven't had the issue with the trigger sticks experienced by those above, but did with the Bog Pod. Fortunately, with the Bog Pod, it was easily fixed by adjusting the clamp screw on the leg section that wasn't holding.
Be sure to practice off of whatever you get, as my wife and daughter have both learned that it definitely is not the same as shooting off the bench, when using ot for hunting. They both found it challenging to hit the targets when in the field off the trigger sticks. But with practice, they are experiencing improved success.
