The only reason I would take it outside the park is if I was going to be buttering on shallow hills. If you aren't buttering or are using steeper hills I definitely wouldn't recommend it outside of park. It'll be a whole lot softer than the pickle. I don't have experience we the garage rocker but I'm pretty sure it's noticeably softer than the park pickle as well.
Okay yeah,I am definitely not getting the artifact Lol now I am between the garage rocker and k2 park star.....
Thanks for all the info!
