Tall Risers in Back

[Sam Gordon]

The Swiss boards do have a cambered flex similar to the arched back of a hissing cat. With a comparatively soft flex to the American equivalent, there is greater inversion when the deck is down-weighted in pump and so approaches a 'bottoming out' situation. This greater flex and liveliness is in part due to the narrowness of the Swiss decks. The narrowness also leads to the feet overhanging the sides of the board so that on a rear-side turn, for example, your heels can touch the ground, throwing off your balance and leading to a world of pain. If the back of a Swiss board is lifted with risers, then you'll find that the front end is more so.

I was wondering why many of the swiss boards i have seen have the back truck jacked up pretty high with risers? What advantages does it have? Is it because of the nature of the high camber?
