I have two Harris S-Bipods, the 6-9 and the 13.5-27. I use the 6-9 primarily for shooting off the bench and the 13.5-27 for all types of hunting. I am very happy with them. One of the best investments I've made cost/benefit wise. I wouldn't dream of going hunting without it now, especially coyote hunting
. I've used a Caldwell and even bought my brother a Blackhawk. Both work and are fine, but I still prefer my Harris over both. I will say the Blackhawk feels pretty solid, more so than the Caldwell I've used. One thing, you might find the 23" height on the Blackhawk a little short. Depending on where I'm sitting and how I'm situated, I need all 27" of the Harris. Either brand will serve you well.....far better than free hand or shooting sticks.
