I'd guess the Formulas are pretty close to the Atlas if not lighter.
I wouldn't have recommended the Formulas if they weren't gonna match up.
For even more response and superb dampening check out the K2 Company. Everything the Formulas have but stiffer, Harshmellow, and an upgraded ankle strap.
Go ahead, drink that kool-aid.
