Casabon is only steezy to the extent that his restrictive, nontechnical style allows him. Going bigger or doing any kind of double is not physically possible for him. This is just not his strength.
So by "pushing freestyle skiing" you are clearly referring to spinning and flipping more. because obviously you cannot be talking about style or railgame, both of which are major elements in freestyle skiing that casabon is pushing harder than most.
the take off is more like you just got water dumped on you and you're standing there with your arms out and shoulders raised with a slightly hunched back
