Demo of the 170 - 12 jumps on it with the WS. Seemed to pack just a little bigger than my other 170 low bulk WS canopy, but did not have to change length of closing loop. Opens quick but soft; I like the snaps as it keeps it organized if the bag comes off funky. Really enjoyed the flare power (as did my ankles) on the Horizon; you can fly it straight in and still have power and easy to do a little speed to increase this.
Had to order one after the demo, exactly what I was looking for and need with the larger canopy for WS's.
