The .600 Ruta Locura poles were engineered specifically for tents that height. Properly engineered carbon fiber tent poles, should be 50%-60% the weight of their aluminum counterparts. If they are not, they are just for specs on paper. Depending on how serious your need is, I can build you a pole that both telescopes for compactness, and is lighter, it can be done. Also, the .600 poles are a standard ferruled section, over ferruled section, which transfers load properly through the axis of the tubes. Using push buttons, cants the sections, does not transfer load evenly, and creates failure points. Also it requires thicker wall sections, because all the load is transfered to a single point where the small button takes all the load. With the tubes having a thicker cross section, along with the larger(unnessary) sections, as mentioned aboved, such telescoping poles offer nothing over good alloy aluminum poles.
