My 13 will have just the stock skid, with Evol 2 shocks all the way around in it. I will more than likely keep it, like I have my 09 with the 860 in it. My son will be ready for it in two more yrs. He rides the 09 now. I keep building new ones and handing the last yrs model down to my wife and then to my son. My wife rides my 12 with the stage 4 in it. The next sled to go will be the 09, I don't plan on getting much for it. but I have got my moneys worth from it. Any way thats my sick way of thinking. I will ride the 13 for 2 yrs Im sure. then send it to my wife or son. It has worked out real well. I dont think I would of snowcheck the 13 if not for them putting in the belt drive. Dam Polaris any way!!
Your very right about the throw in any mods you do to a sled when you sell it. It is almost better to pull everything out and put it stock again. Shocks are easy to take off and put stock back on, even if you just sell them out right. I find it funny that the value of any mods that you do does not carry any real extra value when you sell it, to upgrade. Never have figured that one out.
Oh and plus it gives me two solid sleds for back ups when I wrack one up!!
