Here is another take,
The more track you get, the less fun. A bitter shorter track can be a bit more fun as long as you know how to ride them without getting stuck.
Also, if you get a crazy long track you end up having to go up crazy steep stuff just to find a challenge and that can also get dangerous.
I have a 154" and some times I think it's a bit too long. Yes it's nice and forgiving but less fun. Unless I am in serous silly powderer I actually have more fun on the wifes 137".
I remember the old days when we all had light short tracks and we had a blast in a quarter section. With these big machines now you have to cover a lot of ground to get the same satisfaction.
I guess it all depends on how hard you want to push it.
