i would tell you 'no'. but i ride a 51 horror fk and i really like it. i use it for a little bit of everything except on pow days of course. i guess if you're going to be doing a lot of all mountainy type stuff it might be worth it. i've heard varying views as to whether it stiffer or not. but if you're a park rat the horrorscope is the way to go. but that's just my thinking.
Try this trick and spin it, yeah
Your head will collapse
