Will short and fat skis, long and thin ones, or the biggest or shortest ones possible give me the most stability when l land? Also, what difference will the binding mount location have?
Oh by the way, l have been skiing for years already and have been trying out the terrain park, but it has been hazardous on my current K2 escape 5500s.

shortest possible will give you the most stability

Actually the longer the ski the more stability. But with extra length it makes it harder to spin. Flex of the ski is important as well. A very soft ski will have a tendency to wash out when you land. l would get something about nose high in length and fairly stiff as well.

Yeah l would go with short skis too. Center mounting the bindings will allow you to land switch easier because there is as much ski in front of your boots as in back. It might throw you off a bit going down runs and in the pow at first, but its nothing that you wont learn to deal with pretty fast.

u wanna have short skis with a strong very strong core to absorb the landing instead of ur ankles

Also freestyle boots make softer boots to land in.

You wanna have ur ski bindings further forward for ridding switch. the further back the binding the more u need to lean forward. for pipe u wanna be almost in the middle just a little back. For park l think that in the middle is good for landing on ur tail or nose to soften landing.

Fat skis r for powder the help u stay afloat more & wo not do well on groomers

ok wow guys hes talking about BIG jumps.

if u have small skis, & hit any sizable jump u will definately lose stability. Long skis r more suitable for big airs & big landings. here is a comparison for big & long skis:

LONG SKIS:
Big jumps= big speed. to handle this speed with enough control to throw a trick off a big jump, u want sizable skis. as mentioned by others, the skis flex will greatly alter the stability of landing big jumps. a stiffer ski is more desirable if u focus on big jumps rather than rails & jibs. along with stiffness, u want a long ski for bigger jumps that will carry u faster into takeoff & will keep ur legs balanced in the air. HOWEVER; u also dont want super long skis. for park, try to stay under 190cm. & u also dont want them too skinny underfoot. wider skis r becoming more popular in the park for rails & especially jumps. not just powder any more

SHORT SKIS:
shorter skis r probably more prefered for smaller jumps & especially for rails. u want a ski big enough to be able to ride comfortably (no snowblade-size skis, friends) the smaller ski will be more responsive for rails, & will be easier to spin for small jumps or onto rails. smaller, more style-conscious park skiing will favor smaller skis. but if u try to hit a large jump on small skis. the small skis will feel wobbly underfoot with the speeds required for relaly big jumps. u will also have a tendancey to lose balance in the air, & will have a pain landing because smaller skis usually r alot softer

It is time to retire the 5500's. They are way past their useful life. As to which twin tips to get, use a pair with both ends turned up. They are much easier to use. Remember the Kneissel ''Acrobats'' ?

get sum line skis or armada..the best park/big mountain skis
