I'm a big fan of the new, tall version of the Primos Trigger Stick (it comes in mono, bi, and tripod versions). It is a bit on the heavy side, but it is sure nice if you need to shoot sitting or standing. Most of the areas that I hunt in are areas that have tall sagebrush, and a sitting bipod doesn't work a lot of the time, so I like being able to use one bipod for both sitting and standing if necessary. The tall one also works as a decent walking stick (even thought you are advised not to use it as such by Primos). I also have a Blackhawk prone bipod attached to my rifle so I can take a prone shot if necessary, but, again, I don't end up taking many prone shots because of the terrain I hunt; I just like having it in the event the situation calls for a longer, more steady shot.
I also have a trigger stick that is a tall tripod, and it is set up with a triclawps rifle clamp for when I take a youth out hunting, and that setup works marvelously well. The tripod version also doubles as a glassing tripod if necessary as well.
Again, the trigger sticks are a bit heavy and a little on the expensive side, but they are great for uneven terrain as the legs just slide down and meet the ground at whatever angle you happen to be standing/sitting at and give you great support, which is nice if you are not great at unsupported standing or sitting shots like I am.
