heres what you should be considering:
length:
do you want something head high? a little shorter? a little longer? do these skis have a size that fit your needs? longer skis require a more agressive skier, but are more stable. they dont make as sharp of turns as thier smaller counterparts, nor are they as easy to throw around in the air.
Warrenty:
Do you have a past history of ski breakage? if this is a concern, consider the warrenty on each of the skis your considering.
Flex:
Probably the most imortant chacteristic responsable for how a ski rides. softer skis are better for rails and slower speed riding (easier to initiate carves), as well as flatland tricks like butters and manuals. if you mainly ride park or like real technical ridding, a softer ski will probably work better for you. Stiffer flexes favor high speeds and big jumps. THey will Generally also have more pop in transitions, but not always.
sidecut & Width:
not only does it pertain to how stable a ski will be (again this favors high speeds) and how well it will turn, but it also makes a difference in where the ski should be mounted. granted, you can mount a ski anywhere, but the best riding charcteristics are obtained when a ski is mounted centered with the sidecut. If the skis waist is further up, it will ski better switch, if its further back, it will ride better forward, but not as confidently switch. Also, when you start mounting skis in front of or behind the waist, this is what happens to the handling. Further back= slower turns, more stable. farther forward= quicker turns, less stable. the width of a ski just makes it more stable. a wider ski wont transfer edge to edge quite as fast as a skinny one. and obviously it will get more flotation in powder.
thats a decent overveiw, and you should be able to decide what ski would be best for YOU by using this as a guideline. just figure out what kind of ridding you like the most, and compare it to those skis.
