The 800. I was very tempted by the 1100 turbo, but was just a little worried of the weight issue. Chad at M&M has an 1100 Turbo as a demo and I plan to give it a whirl this season to see what it feels like. To me, what is most important is how a sled feels, not true weight, although weight is a very important factor and can be the number one factor in how it feels.
