New to the site and currently own a polaris and looking to buy my first Artic Cat but have some ? Looking at the F7 and dont know how Artic Cat defines there sleds. The ones I have been looking at say sno pro or fire cat and them some dont say anything besides F7. Is ther a diffrance? And if so what is it? Also some say the 03 are the best year and if so why. One more thing that I have noticed that some are carb and some are EFI. Is one better then the other? Thanks to all that responed.
