So after a nice long search on here i haven't been able to find an answer to my question. I'm shopping for new bindings for my 2014 burton process. I want to get some burtons missions and i noticed that the est missions are more expensive than the non est but the non est come with a disk that allows them to be used on a board with the channel system anyway. if i get a new board later the non est will be able to be used on that board too. the est ones can't. so basically my question is: are the est binding worth the amount of extra money and the fact that they can only be used with a channel board? is there some big difference in feel between est and non est?
