I often use the high, sitting height bipod while shooting prone, which how I do most of my calling. On flat ground it seems higher than optimum, mostly because it is.
On the other hand, much of the time the stubble is too high for the 13” low Harris. Or I’m laying in snow which holds me up but the bipod legs punch straight through to the ground and are too short. Or I’m in rolling hills and have to set up on high ground. I find my position but the ground drops away in front of me and the legs are too short to shoot level. In those cases too high is just right, and just right is not enough.
Maybe its too much to wish for a 27” bipod that would go down to 6 or 7 inches, but I sure could use a higher low. Or maybe make some extensions for a low.
