Harris are quicker to set up but I love the solid feel and the quality machining of the atlas. That being said I have 4 sets of Harris, 2 of which are the 3 piece legs that go up to 27", all have been heavily used and the taller sets have been thoroughly abused. I like to use a low chair with a backrest and lean into them pretty good with my pack in my lap to get above the tall grass when I hike into dog towns. Turned 2 sets of Harris type Caldwell's and a set of stoney points into scrap doing that. The originals have never given me an issue.[/QUOT I usually only shoot off a bench or prone I've never had long legs like what you're saying When I need something that long I just use my trigger sticks for me if I Shoot prone I use a bipod anything I can't see over i use my trigger stick
