_Ryan_im 18 and feel I'm on the lower end of the people my age... however i can still pull some radical maneuvers man.
I'd say being "good" if you're around 18 is being able to:
-270 on to rails
-have front and back swaps consistently
-450's/630's out of rails
-have all 8, consistent or not.
-be able to spin up to a 720 with grab... higher with or without grab
-hit a jump switch
-Corks,rodeos should be in your bag of tricks
-switch onto rails and off jumps
-Confidence to hit or attempt any size of jump or feature
I can't do all of the above but am definitely in the ballpark... I suggest working to attain all of those.
dam, Id say someone who can do all the above is above good.
For me, rail game isn't really an indicator unless you can do 360 sw up, hit any rail switch, and have super feds and such on lock. Doing a 270/450 on is easy as long as you just eat shit a few times. Same goes for all 8, practising pretzing isn't hard.
For me someone's good as soon as he can spin a 7 with a grab, can hit big kickers switch (and land switch) and has at least 2 or 3 inverts with different grabs for each (not counting backflip and front flip, say a flat 3, cork 5/7 and misty).
Being able to pull this shit in the park means you're good, doesn't come easy to be comfortable outside of the pow off axis with various grabs.
Then again it's so subjective, depends where you shred. For all the park shredders at my mountain, you're good as soon as you can hit every feature (we got pretty much everything, funky rails big kickers and pipe) without doing the same trick on everything.
Personally I think someone's good at freeskiing when they can pull a few moves (say 2pretz2, 4 out, a 540 off axis rotation) with
style in the park and not look like a fucking dick when they shred out of the park, know how to go big, and shred pow with ease, drop cliffs...at the end of the day, no matter how hard you shred in the park, if you can't follow me for shit shredding on the rest of the mountain then you're not good (I consider myself pretty good all round). And trick difficulty definitely isn't the biggest factor, I know a freeskier who doesn't go past cork 7 in terms of rotation, and rarely does more than one sw up on the rail. People who can dub 9 still consider him as good as them or better since he's got such a dope style, tweaking grabs and rotation super well and just being super consistent with everything he does, it be taps or butters on.
So to answer your question, if you can't 2 on or spin past a 3 and barely backflip, yeah you're probably below good regarding ns community. But otherwise you're good in general imo.
Tbh, the best skier on the mountain is the one having the most fun.
