Maybe I am wrong??? but no one in the last year has given a definite reason to prove me wrong
The tip in the rail helps for turning and does not hurt flotation other than it will lift the skis faster, I'm talking about the amount of track that will be in the snow running more or less flat. The point you are trying to make is half the pro track is not on flat ground when on hard ground meaning it has half the footprint than any other. Which contradicts my statement of saying it puts down more track than any other skid. The argument that the pro puts down more track from the arc of the rail to the real wheel is what I am talking about, go measure it and prove me right. I am rather getting a kick out of arguing something no one else has taken the time to figure out. The difference is obvious, it may not be what makes all the difference but out of everything it is a very big difference and I think it translates to performance. Now if you guys can get over thinking I am "hate everything Polaris Minded" and open your eyes to all the good I speak of them you might be amazed at what you will find.
Also look at where your feet are when standing to the front of the boards on the pro, the skid puts the track down right under your feet, the cat puts the track down behind your feet. With the right suspension it is the equivalent to the rider input going into the track at a more central weight balanced location of the chassis. The weight of the rider is apply straight down unlike the others where its a teeter toter between the track and skis. Its part of why it handles so well and floats, add that to the right geometry of the skis and a-arms and you have something that was very well developed. For the life of me I can't figure out why after so long the others havent copied it, polaris did it right and its been that way for a while.
SD3, I'm not bashing only comparing for the life of me I can't figure out why you can't get it, SIUYA
