Well, if you ride park all the time...take a guess, if you are at most 60/40 probably big mountain. I think its only for the system though, tip and tall are the exact same, but when you have the system, Park mode is more centered while Big Mountain gives you a little more tip length, but I could be wrong, I've never ridden Heads before, I only give it.
