I use both the 29" caldwell bipod.... and also carry the tall primos trigger sticks. The bipod is good on level ground... but the trigger sticks comes into play when hillsides won't allow the bipod's legs to reach the ground well... or if I need to stand up by a bush or something... that's when the trigger comes in real handy... and the triggers can pivot left... right... and all around because of pulling the trigger.... and bipods and regular shooting sticks can bind you up sometimes during fast action.
