OK well first off, My dad let me ride his f7 for about 100 miles so i have a good feel for the snowmobile. But the one thing that makes me love it so much is that it has crazy low-high end power. Im not one to race on lakes so the high end power doesnt mean as much to me but more low end. But next year my dad said i could get an f5 if i wanted to but i dont want to be disappointed in the power. Will the f5 have as much low end power, as the f7. Lets just say how long can the f5 keep up with the 7 thanks.
