I'd get the Harris S-25C. As already noted, you want something tall enough to shoot over sage, with a swivel for uneven terrain. My brother learned the hard way the importance of having a taller bipod, and I learned the hard way the importance of having a swivel. The S-25C can still be made short enough to shoot prone, particularly if you lay your pack flat and lay the gun across your pack with the tripod legs resting on the ground, and tall enough to shoot over sage. I've done both with my S-25C. Just be sure you practice under both conditions.
