the front one is pretty stiff i have grease in it to keep it from binding up on my t.a so when it gets cold it doesn't move much and i haven't had that happen but the rear was a problem being much smoother it tried to drop when i jumped it so a small strap fixed that problem im sure the same fix would work on the front if it did that too

 oh I see, yeah that looks heavy! thats pretty awesome though, kudos. does the ski ever nose dive in the air? snow manuals?
