I was up in Old Forge, NY Friday and Saturday. On the first day we did 155 miles. I got 17 mpg on the first tank of fuel. The second tank I got 15.5 because I started running it harder. That was the good part. Before I went I put my Simmons ski's on and what a mistake that was. When I got home my whole upper body hurt. The sled was so hard steering that I couldn't wait to get home. On the morning of Saturday I installed my C&A Razor's with 7.5 inch Shapers on it and what a difference that made. I am running 144 1.175 studs on it. The steering was easy and it handled like a dream. With the Simmons on all it wanted to do was push in the corners. The aren't the ski for me!! I must say that my 2007 F1000 LXR had a more plush ride but until everything is settled in my new sled might loosen up some. I do have one question for you though, "What kind of spring length are you running on the front shocks?" Mine seems to want to roll in the corners just a bit. The other thing I have to say about the sled is that it pulls really nice when you start throttling it. I thought I would miss the power of the F10 but this is the perfect sled for all conditions. I only played with it to 80 mph as of now. What will this sled do on top speed?
