The more floatation that you get with the skis, the higher will be the front of the sled when you go into the powder. The higher the front end means that the sled is climbing a hill even though you are on a level snow field. You effectively have a higher angle of attack at the snow and therefore are throwing more snow down instead of behind you to keep your speed up. The more floatation also means that your skis are in less compact snow that is closer to the surface, that also then provides less pressure on the ski to help turn the sled. The deeper the skis are in the snow, the higher the pressure per square inch that the snow exerts on the ski to turn the sled. In summary, sleds with higher floatation skis, trench faster and turn slower than sleds with lower floatation skis. Simmons are higher floatation skis. SLP Powder Pros are lower floatation skis. Simmons however, are better for water skipping. All my opinion of course.
